Restore Windows to an earlier date

When you start your computer, tap the F8 key (F5 on some models) and run your computer in Last Known Good Configuration or in Safe Mode.

The PC boots into safe mode with networking

  • If, despite the restoration, the PC can boot into safe mode but not normal mode, there is probably a hardware or software conflict or infection, if you recently installed software or hardware to uninstall see if your computer starts normally. Then try to scan your computer with your disinfecting software (antivirus ...) as well as online antivirus.
  • If the PC still does not start normally:

download LogonFix and run the executable and that's it. (Nothing happens on the screen, no confirmation) and then restart the PC normally.
