It is recommended to back up the registry in advance and back up the important data of the computer before operation, so as to avoid accidents during the operation that lead to the inability to enter the system and affect the computer data.
2 locate the following registry subkeys:
HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Class\ {4D36E972-E325-11CE-BFC1-08002BE10318}
