Today, I accidentally got something and ran it. In 2 seconds, the desktop was refreshed about 4-5 times. As a result, there was a white unsung icon on the desktop, which could not be deleted, could not be copied, and could not be cut, unable to edit, cannot open, cannot ...... In addition, the "My document" (displayed as the user name in the system after Vista) and "network" icons are missing, and both of them are checked in the Change desktop icon. I searched the internet and found the registry was tampered.
Essentially, items in the Registry under HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Desktop \ namespace \ are deleted or tampered. The following shows the normal registry key value. You can copy it to a text file and name it *. Reg. Then, you can import it to the Registry.
