Option 2 – Manually
1) On your keyboard, press the Windows logo key and the R key at the same time to invoke the Run box.
2) Type cmd and press Shift+Ctrl+Enter together on your keyboard to open Command Prompt in the administrator mode.

Solution 4: Reset or reinstall Windows
If all else fails, you may have to reset Windows, or maybe even reinstall it together. We all know reinstalling will delete all the data on your hard drive, you have to back up all your important files before doing it.
However, with Fortect, there’s no need for lengthy back-ups, support phone calls, or risk to your data. It can reset Windows to the state exactly when it was installed without affecting third-party software.
But treat these options as a last resort, because they both take quite a long time.
