Reinstall the system Note:

If your system is installed on drive C, it's best not to put all your files on drive C. When reinstalling the system, don't change the partition of the hard disk, use drive C as the system disk, and don't touch your drive C under abnormal circumstances.

When installing the program, try to install all the software on disk C, and separate the remaining files from the system files, so as not to delete the wrong program files. At the same time, it is clear at a glance to learn to classify your own files and manage them effectively. If it is really wrong, the worst will be restored.
