Why do you need a password in Windows 7?
The issue of security among most users has been acute and will always be important. And in addition to installing anti-virus software, it is also advisable to come up with an original and moderately complex password, without which it is impossible to boot into the OS for further work on the computer.
But another question is, is this necessary? On the one hand, if only one person has access to a personal personal computer (PC), or if relatives do not “encroach” on private property located inside the machine, then you do not need to set a password. But on the other hand, this is the first necessity in certain situations:
- Several people use the computer.
- Storing particularly important confidential data that should not be shared with others.
- Protection against unauthorized access.
Thus, on one PC designed for several users, you can create the appropriate number of accounts, including the administrator.
But sooner or later, a situation arises when the user forgets the password for personal access to PC resources. What to do in this case? Do you really have to reinstall the OS? But to ensure its reliability, it is advisable to format the partition where it is planned to be placed.
Fortunately, it is not at all necessary to resort to such a radical method, since there are more gentle options. In fact, they will be discussed further.
How to unlock the keyboard
How to block a laptop or restore the operation of its peripherals is a question many users ask. If the process of locking the keyboard does not cause any difficulties for users, then unlocking it may require some skills and abilities. You can unlock the keyboard using a special key combination provided for a specific type of device. Typically, parameters are reset with the following sets:
- Fn + Numlock.
- Fn + F12.
- Fn + F7.
Most often, such combinations work on Lenovo, Asus, and Samsung devices. You can also find information about unlocking in the instructions for use with the keyboard. The second option for resetting the lock is to install specialized software. But in this case, the risk of infecting your computer with viruses increases. Therefore, it is better to carry out the restoration procedure with a specialized specialist.

Disassembly instructions (video too) can be found on the Internet. Provided it dries quickly, the keyboard can be saved in most cases;
- The second type of malfunction (fatal) includes flooding with aggressive (acidic, alkaline, sweet) and fatty liquids. Tea, coffee, wine cause oxidation and destruction of tracks and contact pads. Or, as in the case of milk, they cannot be cleaned - a laptop keyboard can hardly be disassembled, but then cannot be reassembled. You won't be able to clean the keyboard without disassembling it. The main signs that it has been flooded and needs to be replaced are the failure of individual keys or their groups, the appearance of several characters at once when pressing one button, or the printing of incomprehensible characters. All these are signs of a non-working device and a signal for replacement.
A service center can make a replacement (for a lot of money, of course). If you have some knowledge of technology, then you can replace the keyboard yourself. There are a lot of disassembly instructions (especially for popular models).
