How to clean the system disk of Win7 computer? 6 steps to release Win7 C drive

How long has your computer system been cleaned up, even if you regularly clean up, do you really clean up the useless garbage in your computer system? Especially the C drive system disk that we usually open very rarely. Because the computer runs for a long time, the system disk contains many data that we usually use when operating, and the backup file seems to be very important, but it is actually used. There are very few opportunities. It is necessary for us to clean up such files. After all, the space capacity of the system disk directly affects the system's operation. Next, Xiaobian will work with you to give your favorite computer. Perform a general cleaning.

In the first step, we turn off the hibernation function of the Windows7 system, open the “Run” command in the “Start” menu, and enter the “powercfg -h off” command to turn off the hibernation function. (Figure 1), the actual size of this file is the same as the physical memory, which can release 1-3G space for the C drive.

In the second step, you will set the “virtual memory” and click “& computer” to open the “Attributes”. Click “Advanced System Settings”—“Advanced”—“Set”—“Advanced”—“Change" (Figure 2).

This file defaults to 1.5 times the physical memory. After the restart, the settings take effect, which can be released for the C drive. -4G space.

The third step is to delete the automatic backup file. 1. Locate the cmd.exe file (in the "start–> program–>attachment”), right click to select “ Identity Run”2, run the command rd /S /Q c:\\WINDOWS.OLD or rd /S /Q $WINDOWS.OLD3, when prompted to confirm the deleted target WINDOWS.OLD folder, confirm the input y and press Enter key. This is easy to delete, WINDOWS.OLD is the backup file of the system, the longer the time, the larger, more than 10G is normal. It can release more than 3G space for the C drive. (Figure 5)

The fourth step is to clean the C drive regularly, and delete the programs that are not normally used through the control panel — programs and functions. And software, so that about 50M space can be released for the C drive. (Figure 6)

By operating the above four steps, I believe that your C drive space has changed greatly, and it is not cleaned properly. The user of the computer can slim down the C drive at one time and save more space for the system disk. Due to the long-term use of the computer, if the file size of the system disk is too large, it is easy to cause the system to run slowly. Appears, so it is necessary to clean your computer regularly.
