WinSxS folder How to lose weight?

Just now, we shared how to use the DISM Admin tool to view the actual size of the Win8.1 WinSxS folder. For the WinSxS folder, almost every Windows enthusiast recognizes its importance and understands the "remove risk" principle. But this is not absolute.

For example, just a small query on the Win8.1 platform under the WinSxS folder redundancy update, the result of this oversized folder display 6.75G size, volume "amazing" (refer to the figure below). Fortunately, under the latest Win8.1 update platform, we can safely remove the WinSxS folder redundancy update file using the DISM Admin tool, saving less than hundreds of MB, and more than 1G of disk volume.

1, for example, under the Win8.1 update platform, log on to the traditional desktop, right click the Start button, select a command prompt (administrator);

2. Enter the security Cleanup command at the Open command prompt:

Dism.exe/online/cleanup-image/startcomponentcleanup

This command supports earlier versions of the update component (support for Win8.1 RTM, Win8.1 update platform)

Dism.exe/online/cleanup-image/startcomponentcleanup/resetbase

Note: After you complete this command, you will not be able to uninstall the installed updates and will not affect the installation and uninstallation of subsequent updates (Win8.1 update platform is not supported, careful operation)

3, wait for a moment, we re-enter the WinSxS folder query command:

Dism.exe/online/cleanup-image/analyzecomponentstore

Querying the actual size of the current WinSxS folder

Compared to the first time, now the WinSxS folder obviously slimming, from the original 6.75G to 6G size, successful weight loss 0.75G, refer to the above figure.

In addition, the enthusiastic It House forum friend Star2011 also complements DISM to fix Win8.1 image commands, especially when Win8.1 images are corrupted, you can use the Deployment Image Service and Management (DISM) tool to update files and correct problems.

Specifically, open a command prompt (Administrator mode) and run the following command in turn:

Dism/online/cleanup-image/scanhealth

Scan image Check for damage

Dism/online/cleanup-image/checkhealth

Check the damaged part of the image. The report image is in good condition, can be repaired, or is not repairable. If the image can be repaired, you can use the following command to repair the image.
