After that all you have to do is wait for CHKDSK to work its magic. Users can take a bathroom break as it may take some time for issues to be diagnosed. But if it takes too long, CHKDSK might be blocked.


Another cool feature included in Windows is SFC or the System File Checker. This program scans for missing or corrupted system files and repairs them. Users should use SFC as a last resort as it restores Windows system files to their default state. This also includes Windows DLL files, so it is best to back them up.

How to use SFC? Just follow these steps:

  1. Launch the command prompt as administrator.
  2. To check and repair system files, use sfc / scannow.
  3. To just check the system files, use sfc / verifyonly . (No changes made to system files and DLL)
  4. Hit enter.

If SFC finds an error and fixes it, try running the affected program again to see if it works. There may be cases where SFC will find corrupted files but cannot repair them. In such cases, it is best to run the program once or twice.
