Fix 2: Run a DISM Scan

When SFC SCANNOW does not work in Windows, you can try another command line tool provided by Windows - DISM. This tool provides user services and prepares Windows images.

If SFC is stuck, please refer to the following steps to run a DISM scan:

Step 1. Search for CMD on your Windows computer and run it as administrator.

Step 2. Type the following commands in sequence and press Enter:

  • To check the health: Dism /Online /Cleanup-Image /CheckHealth
  • To scan the health: Dism /Online /Cleanup-Image /ScanHealth
  • To restore health: Dism /Online /Cleanup-Image /RestoreHealth

Step 3. Reboot your computer and see if SFC is working properly.

Sfc /scannow solves many problems, but the user cannot use it if it gets stuck at a certain number. We have found users on the forums with the same problem:

Everything seemed to be progressing smoothly after the "Beginning verification phase of scan" appeared. The prompt stopped at 80%, though, and a blinking little white cursor appeared. It's been stuck on "verification 80% complete" for over half an hour. I can use my computer normally otherwise. -from Reddit

We have provided an effective solution to this problem. The most common reason SFC Scannow gets stuck is that the computer has corrupted system files, which can prohibit it from performing tasks related to the SFC/scannow command. In addition, corrupted hard disk data can also cause stuck problems.

In addition, we have summarized some common errors related to SFC:

  • Sfc /scannow gets stuck at validation when starting a system scan - the most efficient way to do this is to replace the corrupted files.
  • Sfc /scannow freezes in Windows - try to restore your computer using a system restore point.
  • Sfc scannow is not responding - Use DISM scan instead.
  • Sfc scannow stopped scanning - Disable the Turbo Memory feature.

Regardless of your SFC-related errors, the best solution is to use EaseUS Partition Master for a one-stop solution. It can solve any problem that SFC SCANNOW gets into trouble.
