2. Scan Health (Scan component store for corruption)
   DISM /Online /Cleanup-Image /ScanHealth
3. Restore Health (Repair the image using Windows Update)

Optional Cleanup Command

To reduce the size of the WinSxS folder after repairs, run:

• DISM /Online /Cleanup-Image /StartComponentCleanup 

Key Tips

• Run as Admin: All commands require a command prompt or PowerShell launched with “Run as administrator”.
• Internet Connection: /RestoreHealth uses Windows Update to download necessary files, so an internet connection is required.
• If RestoreHealth Fails: If Windows Update is broken, you can use a Windows ISO/USB as a source:
  DISM /Online /Cleanup-Image /RestoreHealth /Source:wim:D:\sources\install.wim:1 /LimitAccess (Replace D: with your USB drive letter).
