   • Delete all files in folder
4. Alternative: Use Settings to clear DO cache:
   • Settings → System → Storage
   • Click "Temporary files"
   • Check "Delivery Optimization Files"
   • Click "Remove files"
5. Restart Windows Update services (see Fix #1, step 3)
6. Restart computer and retry updates

Fix #3: Run Windows Update Troubleshooter

• Disable proxy settings - Settings → Network & Internet → Proxy. Disable proxy if enabled.
• Wait and retry - If Microsoft servers experiencing issues, wait few hours and retry.
