2. On the command line as an administrator, execute the command (there must be an Internet connection):

Recovery completed successfully. Operation completed successfully.

3. Next, execute the command:

sfc /scannow

PS C:\Windows\system32> sfc /scannow
System scan started. This process may take some time.
The beginning of the verification stage when scanning the system. Verification 100% complete.
