Fix Windows Errors with System File Checker

If your Windows computer is experiencing crashes, programs that won’t open, or other bugs (Blue Screen of Death/BSOD), the built-in System File Checker is a godsend. When I used to repair PCs, I found that System File Checker (SFC) can fix a wide variety of Windows issues reasonably fast.

Depending on the speed of the computer, it usually takes between 10 and 30 minutes to complete. So before you purchase one of the many ‘repair’ tools online, try System File Checker first.
