Today, I will share with you a skill of using dism command to clean up the backup files updated by WinSxS, so as to slim down the Win8. 1 system. If you open the WinSxS folder under the Win8. 1 system disk (path: C:\Windows\WinSxS), you will find that there are many folders with similar names, all of which are updated backup files of the same application in different versions of history. For example, Adobe is frequently updated.

Player, you can see multiple updated backup files in the WinSxS folder. As shown in the figure:

Then these old versions of the updated backup files add up, which will take up a considerable space. The dism command can clean up the old version of the update backup file, and only keep the latest version of the update backup file.

The method is as follows:

1.

win

+

X shortcut key brings up the system shortcut menu, and select "Command Prompt (Administrator)" to open the "Administrator: Command Prompt" window. Enter the following command in it:

dism

/online

/Cleanup-Image

/StartComponentCleanup

/ResetBase

Supplement: Win8. 1 is no longer supported by this command.

Update if you have upgraded to Win8. 1.

When updating, use the following command: Dism.exe.

/online

/Cleanup-Image

/StartComponentCleanup

Enter, and the command will be deployed automatically after running, waiting for the deployment to be completed. As shown in the figure:

After the operation is successfully completed, open the WinSxS folder and have a look, and you will find that there is only one folder with the same name left. Like Adobe.

Backup file updated by the player. As shown in the figure:

By comparing with the above figure 1, we will find that the original three are reduced to one.

In this way, the volume of WinSxS folder can only be reduced to a fraction of the original size, thus achieving the purpose of slimming Win8. 1 system disk. In addition, you can also try "cleaning Windows Update with the disk cleaning tool that comes with Windows system".
