Hi,
have you tried running the system file checker? If there's any corruption in the system files the SFC will attempt a repair. Right click on command prompt, choose properties then run as admin. Type:
sfc /scannow
Press enter and await results.
If the SFC finds corruption it cannot fix then again in a admin command prompt run this command. Type:
DISM /Online /Cleanup-Image /RestoreHealth
Press enter and await results.
