Some time after installing Windows 7, the user may encounter such a nuisance as a slowdown in the operating system.

In order not to resort to drastic measures and help your PC cope with assigned tasks faster, you can optimize the OS. Often this procedure helps speed up the computer and thus increase its performance.

Fix errors using the built-in Troubleshooter

If your PC starts to run slower, you can try using the Windows diagnostic and error correction program that is included in your computer.

Using this function requires the following sequential actions:

• Open “My Computer”;
• "properties of the system";
• “control panel - home page”;
• "troubleshooting";
• When the menu appears, select the item that is relevant to us (Figure 3).

Checking the hard drive using CHKDSK

Another way to speed up your computer is to troubleshoot problems using the CHKDSK command.

You can do it this way:

• go to the “start” menu;
• select “all programs”;
• open “standard”;
• launch the “command line” console;
• Next, we select the drive that we want to check and fix, most often we start the check from drive “C”, to do this, enter the command “chkdsk /r” in the line;
• A notification should pop up in front of us stating that this manipulation is impossible, due to the fact that in this case we press the letter “Y” on the keyboard;
• we reboot the computer, at startup we see a blue screen with a running timer, wait, the system will start without failures (Figure 4).

Disk optimization and defragmentation

To achieve the highest results in speeding up the OS, you can additionally perform defragmentation after checking and optimization.

You can carry out this procedure using a Windows 7 error correction program downloaded from the Internet, or you can use a service that is already on your computer. We carry out the procedure in the following sequence:

• click “start”;
• "all programs";
• "standard";
• "official";
• "defragmentation".
