Like everything else in Microsoft Windows, there are multiple ways to run the Windows 10 system file checker. Today I am going to focus on the fastest and easiest way to run the system file checker in Windows 10.
1. First, you will want to right-click on the start menu and choose Windows PowerShell (Admin).
2. Once you have the PowerShell open with administrative privileges, you will want to type in sfc /scannow and hit enter. The file checking process will now begin checking the Windows 10 files for errors and corrupt/missing files. If you have a modern PC with an SSD this won’t take too long.
3. If your system came back 100% complete with no errors found like mine in the image above, you can be confident whatever issue you were facing was not caused by corrupt files in your Windows file system.
4. If, however, it came back with errors found that it wasn’t able to fix, you will need to continue with step 4. You will now need to type in DISM.exe /Online /Cleanup-image /Restorehealth (note the space before each “/”) and then press Enter. This step will take some time, but it should restore all the missing/corrupt files on your Windows system.
5. Once that step has finished, and all the Windows files have been fixed/restored. You can now double-check by once again entering in sfc /scannow. That’s it. Your Windows 10 files should now be back to 100%.
