There are generally two ways to lose weight on disk C, one is through third-party software, such as 360, computer housekeeper and the like, and the other is the cleaning program that comes with the computer. I recommend you to adopt the second method here, and the specific method is as follows:

1. Open my computer, right-click Properties, and then click Disk Cleanup.

2. Wait for the processing result, and finally the following interface will pop up, prompting to clean up files, which are generally files updated by the system and can be deleted directly without any impact on the system.

3. Click Clean System File in the lower left corner of the above interface to get the following file, select other options, and then clean the following restore point. In this way, drive c can generally lose a few g spaces. If you haven't cleaned up the restore point, you may lose more than a dozen G spaces.
