Resolution

Windows 8.1 or Windows 8

Step 1: Use System File Checker to repair damaged Windows files

1. Open an elevated command prompt.

Step 2: Run the DISM tool

If the problem continues, use the Deployment Image Servicing and Management (DISM) tool to fix Windows Update corruption errors. To do this, follow these steps:

1. Open an elevated command prompt.
2. Run the "DISM.exe /Online /Cleanup-image /Restorehealth" command.
   Important When you run this command, DISM uses Windows Update to provide the files that are required to fix corruptions. However, if your Windows Update client is already broken, use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files. To do this, run the following command instead:
   
   DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
   Note Replace the C:\RepairSource\Windows placeholder with the location of your repair source. For more information about using the DISM tool to repair Windows, reference Repair a Windows Image.
