How to restore failed Windows 10 activation

Reasons why Windows 10 activation expires

Windows 10 activation may have failed for the following reasons:

you upgraded from Windows 7/8 to 10 or reinstalled Windows 10. After such actions, Windows must require a product key. This is done to prevent the same copy of the OS from being used on an unlimited number of PCs/laptops/tablets. After installation, you need to immediately activate Windows 10 over the network;
you upgraded your PC by changing the processor, motherboard or RAM. Unlike Windows XP/Vista/7/8/8.1, where you could enter one activation key on any PC an unlimited number of times, Windows 10 is “tied” to the computer ID (by hardware), which is formed based on a set of components. Any replacement changes the PC ID. To fix the problem, you will have to contact Microsoft technical support.

Ultimate PID Checker

You can also use the Ultimate PID Checker utility to check your licenses. But this program is only useful for versions of Windows XP, Vista, Windows 7 and 8/8.1, including all variants.

In addition, the utility analyzes the MAK (Multiple Activation Keys) counter, which documents the ability to activate a multi-user license.

If the licenses are in a text file in TXT format, Ultimate PID Checker can also check multiple Windows keys at the same time.

In addition, it is important to understand that after the rollback, the system version may have changed. For example, during the rollback, a version with service pack SP1 was installed. In this case, the license key available in the registry of your system will not be suitable for it. Microsoft specialists say that if you still want to get a license in this case, you will have to look for it from third-party suppliers of OEM versions of the system, which may still be available somewhere. In this case, we again return to the third option, as the easiest solution.

How can I tell if a Windows key is being used on another computer?

There is a question from Sveta on this topic:

Good afternoon My name is Sveta, I am from the city of Kyzylorda (Kazakhstan), please help me find out if my key is used in another computer. More precisely, I buy a Windows 7 Ultimate system from a store, they install it on my computer, and after 3 years I reinstall the computer, but I can’t get the key into the computer, I can’t, although I didn’t change the motherboard in the computer. This happens, what should I do? Help me in this matter.

Sveta most likely has just such a case. The system was reinstalled, but it’s unlikely to be a hardware issue, so whether the motherboard was changed or not doesn’t matter. The only thing that matters is the version of the operating system. In this case, you can try installing another version of Windows 7 Ultimate - for example, without SP1.

Restoring Windows 10 activation

There are several ways to resolve the issue of failed Windows 10 activation:

contacting Microsoft support and reactivating Windows 10 online or by phone;
Participation in the Windows 10 Insider Preview program. This method is suitable for people who constantly monitor the latest Windows updates;
updating Windows 7/8 to 10 from the Windows Media Creation Tool application (before this you should reinstall and activate the previous version of the system).

Restoring lost Windows 10 activation by reactivating

After reinstalling the OS, activation is checked again. If the connection disappears or freezes at this moment, the license key verification fails. If automatic activation fails, do the following:

Give the command “Start” - “Computer Settings”. Go to computer settings
Select Windows 10 activation settings. Check if Windows is activated
Enter the Windows 10 product key you already have. Enter the key included with this copy of the OS

Windows activation will be verified and restored if you already have a Microsoft account and the Windows 10 key is valid. If there is no account, Windows will prompt you to create one. Return to the previous OS settings window, select “Accounts” and follow the instructions in the Windows wizard to register a new user with Microsoft.

Enter your details, for example, e-mail or Skype login

Return to the familiar Windows 10 activation window and try again by entering the correct Windows key.

Activating Windows 10 using the Slui.exe software module

The application and its process of the same name slui.exe is an auto-running software module built into Windows that maintains the OS in the “system activated” status.

The Slui program runs in the background. It starts and shuts down on its own (controlled by the Windows Task Scheduler and built-in levels of protection).

It is not always possible to find Slui in the Task Manager, but every user can independently launch the process C:/Windows/System32/slui.exe and see how this program works.

The Slui icon is original, so it is easy to find it in system folders

Do the following:

Run the slui.exe file in the C:/Windows/System32 folder.
Select the country or region where you live. Click the Next Steps button in the Windows 10 Activation Wizard
Provide your Microsoft support representative with the installation code. This random number is the serial number against which your copy of Windows 10 will be verified. Dictate the installation code to the activation service employee
Enter the key you received from your support representative. This is an alphanumeric cipher generated by Microsoft security. Write down and enter the code received from the Microsoft operator
Exit the Slui program by clicking the end activation wizard button. The Windows 10 Activation Wizard will exit after you click Finish.

The goal of any activation method is a Windows 10 system registered with Microsoft and ready for full functionality. Give the command “Start” - “Settings” - “Update and Security” - “Activation”.

Windows 10 crashed unexpectedly

Check the status of your copy of Windows 10.
The Windows 10 security tool will indicate successful activation.

Calling 8–800–200–80–02 is free from any phone from anywhere in Russia. This method, including activating the OS over the Internet, has been known to users since the days of Windows XP. A variety of options for activation methods “unloads” Microsoft employees: there are billions of Windows users, so it makes more sense to keep an automatic activator.

Termination of activation after changing Windows 7/8 to 10

If the previous activation key for Windows 7, which could have worked on the “ten”, was lost, then until January 16, 2022, you could do the following:

Reinstall the version of Windows 7 that you had before upgrading to Windows 10.
Switch to Windows 10 through the loyalty program (for people with disabilities).

Immediately after the free upgrade period to Windows 10 ended, a website was created designed for users with disabilities. However, it ceased operations on January 16, 2022.

Reinstall Windows 7/8 again from the same source (DVD media, installation flash drive or memory card) by going through the standard Windows 7/8 activation procedure by calling Microsoft support. Then perform a standard upgrade to Windows 10 using the Media Creation Tool application, available on the corporation's official website.

In case of system crash, write Windows 10 to external media. Upgrade from Windows 7/8 to 10 with its help.

To update the system without a flash drive or external drive, do the following:

Start your Windows 7/8, download and launch Windows 10 Media Creation Tool.
Select "Update this PC now." Select "Update this PC now"
Accept the terms of the agreement with Microsoft. Accept the Windows 10 publisher's guidelines
Keep personal files and Windows 7 apps compatible with Windows 10. Choose to keep personal data and programs in Media Creation Tool
The Media Creation Tool wizard will download a licensed copy of Windows 10 (currently this is build no lower than 1703 Creators Update). Wait until the installation program finishes. Wait for Windows 10 Media Creation Tool to finish
Wait until the image is unpacked and Windows 10 is installed “on top” of Windows 7/8. The installer will copy Windows 10 files to drive C
Wait until the Windows 10 Welcome screen appears. Click Continue to finish the Windows 10 Setup Wizard
Enter your old password previously set in Windows 7/8 (if any). Enter your password set back in Windows 7/8

The Windows system has been updated to "ten". Right-click on Start and select System. Review your Windows build and license activity information.

Explore Windows 10 system information

This is the most affordable and guaranteed way to update the system without losing the key of the previous product (Windows 7/8). If you decide to simply copy the necessary files to external media and “clean” install the “patched” Windows 10 (1709) Fall Creators Update, then you don’t have to follow the instructions described above.

Get Windows 10 through Insider Preview

Receiving build 1709 of the Fall Creators Update using the Windows Insider Preview requires you to register with the server insider.windows.com. This may require a Microsoft account.

Click Start - Settings - Update & Security - Windows Insider Program and click the Start button (it will change to a Stop receiving Insider Preview builds button). Windows Insider Preview lets you evaluate new builds of the Tens and decide whether to stay with them
Microsoft will ask you to log in. Without logging into your account, the update to the latest build of Windows 10 will not occur. Enter your login or e-mail along with your password
Choose to get the latest build of Windows 10. Choose to download the latest build of Windows 10
Choose the late access option (the ability to “roll back” to a previous build if you don’t like this one). The late access option will allow you to evaluate the latest build of the “ten” without making significant changes to the OS
Restart Windows 10 and give the command “Start” - “Settings” - “Update and Security” - “Windows Update”. The latest build of Windows 10 can be downloaded and installed while the PC is running

Windows 10 updates will not affect the key of the OS itself. You can continue to work as before, with timely updated functionality, programs and components of Windows 10 at your fingertips. You can opt out of receiving further updates at any time by going to the familiar Windows 10 Insider submenu and clicking the “Stop receiving Insider Preview builds” button "

The main thing is to understand the cause of the problem. Sometimes Microsoft itself becomes the culprit of the error. But whatever the reason, restoring Windows 10 activation is easy if you know how.

Activating Windows 10 - All legal methods in 2017

During installation of the Windows 10 distribution, the software product is activated, which allows the user to fully use all the capabilities of the operating system. The activated version of Windows 10 makes it possible to avoid such unpleasant problems as periodic sudden reboots, the inability to configure your profile, and a constantly pop-up watermark reminding you of the need for activation. The activated product enjoys official support from the developer. But sometimes an event occurs such as the termination of the activation. This can happen for various reasons, depending and not depending on the user's actions. Then the question immediately arises of how to restore the failed activation. Until activation is restored, working with the deactivated version of the system will not be entirely comfortable or correct. It is for these cases that the developer has provided a number of specific actions, by performing which you can restore activation.

kmsauto interface

The application interface is simple and intuitive. Moreover, it is also in Russian. Simply paradise for a novice user. However, you need to figure out which button does what. It's better to start from the main window.

The “Activation” button is used to start the process. After clicking on it, a selection of products to activate will appear. Just click on the one you want.
“Information” provides basic information about the installed OS and license status.
The console will display the activation progress.
The green inscription “Auto” indicates that the activator is operating in automatic mode.

There isn't much information in the main window. There is much more of it on the “System” tab. It is worth considering it in more detail.

The first block is responsible for manual installation or removal of KMS-Service. In general, this entire tab is intended for manual activation of the OS or Office.
The second block creates a task in the scheduler to automatically activate Windows and Office after a certain number of days.
The third block is intended for manual installation of the required key into the system and software product from Microsoft.
Block No. 4 allows you to reset the application settings to standard and change the interface language.

However, the activator also includes an “About the program” tab. It is purely informational. Provides basic information about the activator itself and its developer. There is nothing useful in it.

The beauty of this activator is that it can work in both manual and automatic mode. But which one to choose depends entirely on the user. There is one caveat: Manual mode should only be used if you know what you're doing. Otherwise, you can do an incalculable amount of trouble and “kill” the system.

Why does Windows 10 activation stop working?

Unlike previous editions, Windows 10 uses a completely new algorithm for activating the distribution installed on the computer.

When purchasing a licensed distribution kit in a store and installing it on a computer, the user enters the license key only once . After the first activation, information about the system and its components is stored on Microsoft’s activation servers and subsequently the activation process on this computer will take place automatically during any reinstallations.

If the installation of Windows 10 was carried out during an upgrade from older operating systems Windows 7 or 8.1, then the Windows 10 installation program checked the current activation status and generated a digital license on the activation server.

At the same time, a unique computer identifier was created and information about the electronic components of the device was saved. When you reinstall the system, a digital license will allow you to automatically activate the distribution. This activation mechanism makes it possible not only to reinstall Windows 10, but also to perform any operations with the hard drive, including formatting. In any case, the system will be automatically activated upon first startup by contacting the activation server.

Despite such a well-thought-out activation algorithm, sometimes it fails. In this case, the activation simply ceases to operate and the system begins to be considered deactivated, with all the ensuing consequences.

When activation expires, the message “Evaluation copy. Expires...", which means. that the version is a trial version and expires at the specified time

Unfortunately, the developers of the tenth edition of Windows were unable to foresee all situations that would affect the activation process and its possible failures. Activation may no longer be considered valid after reinstalling Windows 10, updating any program components, or replacing the computer's motherboard. These are the most common cases of termination of the system activation status.

To return the activation status, the developer has established certain rules for users. In addition, there are additional ways to activate the system.

Overview of all Windows activation errors and solutions

Termination of activation after reinstalling Windows 10

Termination of Windows 10 activation after reinstalling the system occurs on computers that do not have access to the Internet, as well as in cases where, when the computer accesses the activation servers, a connection is lost or access to the server fails. In this case, it becomes necessary to go through the activation process again. There are two ways to do this.

We recommend that you read

The first is using a 25-digit license key received when purchasing a Windows 10 distribution in a store.

Connect to the Internet. In the service menu of the “Start” key, click on the “Settings” icon. In the Start menu, click on the Settings icon
In the “Options” panel that opens, go to the “Update and Security” option tab. In the “Options” panel, click on the “Update and Security” icon
Select the “Activation” line on the left and click “Change key” on the right side of the panel. In the “Activation” tab, click on the “Change product key” icon
Enter the 25-character key and click Next. In the “Product Key” field, enter the 25-digit license key
Activate the system:
If you have not created an account, it is recommended to create one. In the white field, enter your email, Skype or phone number to register and create an account
Once you create an account, all activation information is tied to that computer on the Microsoft activation server.

The second way to go through the activation process again is to use a utility designed for digitally licensed versions.

Connect to the Internet. Go to the “Start” menu and select “Run” from the service menu. From the Start menu, select “Run”
In the “Open” field of the “Run” panel, enter the command interpreter slui.exe 4. In the “Open” field, enter the command interpreter “Slui.exe 4”
In the panel that opens, select your country and press the “Next” button.
In the next window, enter the activation code by calling the phone number indicated on the panel and follow the answering machine prompts to activate the system.

Please note that only those users who have already activated Windows 10 using a key or received a digital license when upgrading from older editions of Windows can activate by phone.

Termination of activation after updating Windows 10

If, after installing Windows 10, the option to automatically update the system was not disabled, then all updates that periodically come to the computer from the developer will be installed automatically. When updating, a very important point is a reliable Internet connection. If, when updating system files, it was not possible to connect to the Internet, the connection was unreliable or periodically lost, or the Microsoft activation servers were at some point overloaded, then a failure could occur leading to the termination of the activation status, after which the system begins to be considered deactivated.

Restoring the activation status can be done in two ways - using a utility for working with a digital license or using a license key received upon purchase. In addition, it is possible to install the new release of Windows 10 from the Microsoft website.

On the official Microsoft website, go to the “Products” tab

In “Products” go to the Windows tab, in the drop-down menu select Windows 10 and then “Move to Windows 10”.

Select the “Move to Windows 10” tab

Activation servers store data about the identification status of your computer after the last installation of the system. Therefore, a clean installation will not require you to enter a license ID key. After installation, it is recommended to create installation media on a DVD or USB drive in order to be able to perform a system recovery.

Termination of activation after replacing the motherboard

When Windows 10 is activated for the first time on the Microsoft activation server, it is linked to a computer and a unique identifier is created, which allows you to use only a digital license in the future and makes it possible to do without a 25-digit license key. Microsoft does not publish the algorithm for generating this identifier anywhere, but it is known that it is tied to the system motherboard. Thus, you can safely replace components such as a video card, hard drive or RAM if they are installed in the appropriate connectors on the motherboard. If the motherboard is integrated or activation was carried out with an additional network card, then problems may arise when replacing them. When replacing the motherboard, it will definitely be considered by the Microsoft activation server as a new computer, not tied to the installed Windows 10 . In this case, you must contact the hotline or Microsoft support. If you have a licensed copy of Windows 10 installed, then the issue will be resolved in your favor.

If the antivirus program interferes with activation, you can temporarily disable it or add activation files to the antivirus exceptions.

Command line

The command line itself does not restore anything, but it makes it possible to launch other tools. So, with its help we can open Windows Explorer to see the installation location (partition letters in the recovery environment and during normal system booting usually do not match), run the system file error fixer, registry editor and bootloader recovery utilities.

If rollback to a checkpoint and auto-recovery at startup (the first and second options) did not give the desired result, the console utility BCDBoot often helps to increase the loading of the “tens”. It recreates the hidden “System Reserved” partition and copies boot files from the Windows directory to it.

For BCDBoot to work correctly, you must specify the location of the Windows folder on your hard drive. To find out, you can use the Diskpart utility, but I find it more convenient to do this through Explorer.

So, to get into Explorer, let's open the command line and launch Notepad in it.

While in notepad, go to the “File” menu, select “Open” and go to the “This PC” folder. Next, let's go through the disk partitions and determine which of them contains the system directory. In my example this is drive D.

Next we return to the command line and execute the instruction:

BCDboot D:Windows

Please note that your path to the system folder may be different.

In 80% of cases, this is enough for the “ten” to start normally. But in about 20% of cases the command does not work correctly - it does not restore all boot files. To help the utility a little, before executing the instructions on the command line, you need to format the reserved boot partition (in my example, drive C) in FAT32. This can also be done using diskpart, but I find it more convenient through Explorer.

The following two console commands recreate the boot records of the entire drive (MBR) and the system partition (VBR). They are used to solve problems with running Windows on MBR disks.

Execute commands one after another in this order:

bootrec/fixmbr

bootrec/fixboot

If you accidentally run them on a GPT disk, nothing bad will happen.

In some cases, startup problems arise due to damage not to boot files, but to the main system files, for example, after a virus attack. As you may know, Windows has a special utility called Sfc to fix them. exe. So, thanks to the command line, you can also run it in the recovery environment.

The command to find and fix errors in protected system files in the recovery environment looks like this:

sfc /scannow /offbootdir=D: /offwindir=D:

The offbootdir parameter determines the location of the main boot partition (in my example, as you remember, this is drive D), and offwindir is the path to the system folder.

Using the command line, you can also fix registry errors on an unbootable system. But, unlike previous instructions, this requires certain experience and qualifications, because the user needs to know exactly what to correct and what erroneous entries should look like normally.

I will not dwell on registry errors that lead to Windows 10 boot failure, since this is the topic of a separate large article. I will only describe the method for launching the RegEdit editor. exe in the recovery environment and open the registry files in it so that you can fix the errors that you are aware of.

So, to launch the editor, write the word regedit on the command line and press Enter.

You will see that in the utility window that opens there is already some kind of registry, but not the one you need. Before us is our own registry of the recovery environment, and we are interested in the main system.

What to do if Windows 10 activation is lost

If the user is unable to restore the missing activation of Windows 10 or he has not previously switched from the old edition, but now he has finally decided and does not have a digital license, then there are two ways to activate his operating system. Each of them has its own advantages and disadvantages.

Connecting to the insider program

The insider program makes it possible to legally obtain a new edition of Windows 10 without having a digital license obtained when upgrading from an old edition of Windows 7 or Windows 8.1, or entering a 25-digit license key. The program is designed for preliminary evaluation and testing of a new software release. Participants have the opportunity to work with a licensed edition of the program, but they must keep in mind that the assembly with which the user will work has not been completed and has certain inconveniences in use. The digital license of the test edition will not allow activation of the system in the same way as real holders of a license key or digital license . A watermark will often appear at the bottom of the desktop reminding you to activate, and new releases will often arrive, which will take time to update the system. You can connect the test program from a “pirated” or unlicensed version of Windows 10 when it begins to request activation.

To enroll in the Insider Preview program and become a legal Windows 10 user, you must do the following:

Using the Start key's Services menu, expand the Settings panel. In services, click on the “Settings” icon
Go to the “Update and Security” tab. In the panel, click on the “Update and Security” icon
Select the Windows Insider Program icon. In the panel, select the “Start” button
Click the "Start" button. We are waiting for the download of the insider assembly to finish
After downloading the Insider version, restart your computer. The legal edition of Windows 10 is installed.

You can also connect to the insider program through the official Microsoft website.

Register on the Microsoft website under the Windows Insider Program tab. Select the “Windows Insider Program” icon
Fill out all required information. Press the button “Register a personal account”
Download the Windows 10 distribution and install it on your computer.
During installation, log in using an account registered with Microsoft. Enter your account
After this, activation will occur and a digital license will be created.

The official website of Microsoft Corporation is not entirely convenient to use, especially when searching for a product. First you need to understand its structure in order to understand where and what to look for.

Software activation of Windows 10 edition

There is another way to activate Windows 10 using a third-party activator. Whether to use it or not, everyone decides at their own peril and risk.

The most reliable and widely known KMSAuto Net activator for Windows 10 actually works. Its use is the best solution to activation problems. A legal activator, contrary to popular belief, was created for the corporate segment and is used to activate Microsoft software products .

The main advantages of the utility:

speed work;
clear interface;
the ability to configure the utility;
presence of a help system;
ability to install product keys;
additional tools.

The utility is universal, but, as practice shows, sometimes activation ceases to be effective after 180 days. After this, the product key needs to be replaced. Before you try to restore the activation status of Windows 10, you need to determine whether the installed version has a 25-character license key or an electronic digital license.

After downloading the utility, run it using the KMSAuto.exe file.
Click on the “Activation” button. In the utility window, click on the “Activation” button
In the next window, click the “Windows Activation” button.
Wait for the activation to complete. This is indicated by the appearance of a line in the lower half of the window “Your system is in an activated state.”
Restart your computer. System activation is complete.

Video: Activating Windows 10 using KMSAuto Net

If the user has installed an edition of Windows 10 on his computer at least once or upgraded from an old edition of Windows, then the identification status is saved on the Microsoft activation server. This allows you to reinstall the system multiple times. Reactivation is not a common case, but you need to be prepared for it. When restoring, special attention should be paid to the termination of activation when replacing the motherboard and remember that after this it is necessary to restore it using a digital license.

August 16th, 2022 Denis Dolgopolov

Activated Windows 10 may lose its status if changes occur to the system or computer components. In some cases, activation can be returned, but first you need to find out the reason for its loss.

When flying after updating or reinstalling the system

Have you already regretted your decision to update your operating system? After updating Windows 7 to Windows 10, there are cases of bugs such as activation failure. Here is a detailed step-by-step guide to system recovery:

We go to the control panel of the former system.
Find the “Programs and Features” column.
Click “View installed updates”.
In the list that pops up, select KB971033.
We get rid of the extension using the “Delete” button.

After restarting the PC, you just need to activate it again. Certain applications are designed for such operations. Their work occurs when the antivirus is turned off, due to the fact that they interact with system files. Below we provide a list of previously tested programs:

Chew7 – the creators thought through everything from the very beginning to the finale.
KMSAuto. A very useful tool in case Windows 10 activation fails. But only when choosing this utility, carefully read the conditions, since not every version works with Windows.
Windows Loader. The only thing you need to know about the progress of the activator is that if the color of the circle that appears at the very beginning is green, then the program will continue recovery.

Updating the OS using the Media Creator Tool

Another option is what to do if Windows 10 activation on your computer or laptop fails. The recovery method when switching to the current OS occurs is to use a special application.

The Media Creator Tool utility was specially created by Microsoft developers for the transition from older operating systems to more recent and new operating systems. Currently this is a migration from Windows 7 or 8 to Windows 10.

There is no need to use flash drives or installation disks here. The algorithm of actions is as follows:

run the old operating system;
download the application from the official website;
run computer update now;
agree to all terms and conditions;
save personal data from the old OS;
wait for the automatic download of a licensed copy of the operating system;
wait for the process to complete.

On average, unpacking and installation takes about 15-20 minutes. Once the user welcome screen appears, the process is complete.

To log into an account that the user created earlier, you only need to specify your own secret password.

Insider Preview utility

Users have another activation tool at their disposal. With Insider Preview you can get your hands on the new OS build. But here you will have to register on the official Insider Windows server. It is important that the user has a Microsoft account.

To restore activation, you must:

via “Start” open the “Updates and Security” menu;
start the preliminary assessment program by clicking “Start”;
go through the authorization procedure;
wait for the process to complete;
to restart a computer;
check for OS updates.

If we are talking about official OS updates, they should not affect the key in any way.

Why does activation fail?

Some time after successful activation, you may receive a message that your system is not licensed. In most cases, along with the notification, a unique error code will be presented, based on which you can find a more detailed reason for the activation failure and a method to help return everything to its place. Typically the code consists of letters and numbers, for example, 0xC004C003.

Sometimes an error occurs with code 0xC004C003

The second reason for activation failure is the replacement of computer components. Activation is tied to the motherboard, and each board has its own unique number, so if you replace this part even with exactly the same model that was in the computer before, the system status will change as soon as it notices the replacement.

A message may pop up stating that Windows has lost its activated status.

Activation may have failed due to uninstalled updates. Update your system to the latest version via Update Center to check if this is the problem.

Installing available system updates

And the last reason why activation could be lost is an incorrect transition to a new version of Windows. That is, for example, if you upgrade from activated Windows 7 to Windows 10, then activation according to the rules should remain. However, this may not happen if you use the method of removing the old operating system and installing the new one on an empty hard drive.

It's better to prepare for the worst in advance

Since 80-90% of cases of Windows 10 not starting are due to software failures, today’s article is devoted to methods of dealing with them.

:/> Programs for amplifying sound on a computer, laptop

So, to restore normal Windows startup, the computer needs to be booted into the recovery environment. If you have previously used Windows 7, then you know that this very environment is installed on the disk along with the main system. And to enter it, you need to open the menu of additional boot methods (by pressing F8 after turning on the computer) and go to the “ Troubleshooting” section.

The “top ten” also has a recovery environment, but since its loading time has significantly decreased compared to Windows 7, the interval when you can call the boot menu has also become much shorter. There is only one chance left at this time to press the desired key (more precisely, the combination of F8 and Shift): if the system is installed on an MBR hard drive and the fast startup option is disabled in the power settings of the PC or laptop. If the system is on an SSD or GPT hard drive, you will need bootable media.

For emergency recovery of Windows 10, it is optimal to keep its official distribution on a DVD or flash drive, and of the same bit size as installed on the PC. As an alternative, you can use the MS DaRT 10 utility download package (Microsoft Diagnostic and Recovery Toolset for Windows 10).

MS DaRT distributions (formerly called “ERD Commander”) are officially distributed only through a paid subscription, but they are easy to find on the Internet. For example, on torrent trackers. Windows 10 images are available for download from .

As an example, I will use the home edition of Ten, recorded on a bootable USB flash drive, since it has everything you need.

Return activation

In all the above cases, you have a chance to return activation. To use them, try the methods given below for each case separately.

If there is a code

If you were presented with a unique error code along with the activation failure notification, then use it to find the correct solution to your problem. In most cases, errors with codes are eliminated by re-activating:

Open PC settings.
Open computer settings
Select the "Updates and Security" block.
Go to the “Updates and Security” section
Go to the “Activation” sub-item and change the product key: reset it and re-enter it.
Click the “Change Product Key” button
Launch the Run window using the Win+R key combination.
Launch the “Run” window
Use the slui 3 command to proceed to online activation.
In the window that opens, follow the instructions provided by the activation wizard. Execute the command slui 3

If this method does not help, then find a more individual method on the Internet, guided by the existing error code.

When replacing components

If you replaced the motherboard, then according to the rules of the Windows 10 EULA, your computer should be counted as a new device. That is, the key that you used to activate the system running on the previous motherboard will receive the status of used and will not be suitable for re-activating your computer with a new board.

But there are situations when Microsoft support service meets users halfway and activates the system in case of board replacement. To contact the operator and communicate with him, use system activation by phone by entering the slui 4 command in the “Run” program, which can be opened with the Win + R key combination. During the activation process, you will contact the operator. When this happens, explain to him that you had a licensed system and already purchased a Windows 10 key, and then follow the instructions provided by him.

Execute the command slui 4

When flying after updating or reinstalling the system

If you purchased a computer with an already installed and activated system (OEM), then you most likely do not have an activation key. But it is built into the BIOS, so the system will automatically activate when it realizes that it is there. But the key located in the BIOS is only suitable for activating the operating system that was installed when you purchased the computer, so you will have to install it, activate it, and only then update to Windows 10 again. If, after installing the old OS, activation does not occur automatically, you will have to contact contact the technical support of the laptop manufacturer or the company that sold you the computer and ask them to restore the license key. You have the right to this because you bought their product with an already activated OS, which means its cost was included in the amount you paid.

Almost the same actions should be performed if you activated the previous operating system installed on your computer yourself: install the old Windows for which you have a license key, activate it, and then upgrade to Windows 10, the activation will be transferred automatically.

Activation problems can be resolved in the following ways: by re-activating, calling Microsoft technical support, or re-upgrading from a previously activated system. If none of these options help, then you should contact Microsoft support through their official website, describing in detail the cause of the problem and the methods that did not help resolve it.

Settings

Why can't I activate the system automatically? This can happen for various reasons:

The activator was not launched with administrator rights (this is important).
The antivirus has quarantined KMSAuto Net.
NET Framework 4.5 is not installed.
Various types of errors appear.

Before installing or uninstalling a service, you can also make some settings.

If necessary, check the boxes for logging and determining the IP address.
WinDivert - in this mode the service will be installed along with a special driver.
Hook - installing a service and replacing some system files.
TAP - installation of the service along with an additional virtual network card.
Auto — install the service manually or using one of the above methods. Recommended for novice users.
NoAuto - installation of the service without making any changes to the system. Not the best option for novice users.
If after making the settings the system does not activate, you can reset the settings to the default settings and try again.
It is necessary to activate Office and create a scheduler only after successful activation of the system.

For more curious users, in the “Settings” section there is a button “I don’t have enough settings” - click on it.

Initially, you need to uncheck the “Delete IP KMS-Service” item - this item means that after activating the KMS, the service will be deleted and subsequent reactivations will be impossible.
If desired, select: screensavers, sounds and other items in the “Settings” section.
In the “KMS-Service Settings” field, set the port. The default is already 1688, you can change it to your own or leave this one.
Set PIDs for the system or office - select what to activate and click the “Generate ePID” button.
The AI parameter means the period of automatic reactivation in case of an unsuccessful attempt. The default value is 43200 minutes, that is, 30 days. That's a lot, put it at 100 minutes.

How to use?

How to use KMSAuto.net? Thanks to Russian language support and an intuitive interface, users practically do not have such a question. However, in order to correctly activate the system, you will need to study the instructions below. So, download the software, install and launch, the following window opens.

The text line indicates the current state of the system. Since the program runs on a licensed copy of the operating system, the message is appropriate. On an unhacked OS, a message will be displayed indicating there are problems.

To activate the system, you need to click on the large “Activation” button and select the appropriate item. On pirated copies of the system, the button works.

When clicked, the hacking process begins - we are informed about this in the blue lower window.

After 5 seconds the procedure is completed and the software receives a license.

The same can be done with another Microsoft product – Office. In the appropriate section you need to select “Activate Office”.

Attention! The KMS activator allows you to access the full version of Office 2003, 2007, 2022,2021, 2022. And also hack Office 365.

Now you know how the Windows 7 ultimate x64 and x86 activator application works. By analogy, a block is removed from the Windows 8.1 OS - there are no differences in the process. In most cases, the above steps are enough to install a product key, but this program is flexible and offers different settings.
