Windows Update Troubleshooter

Windows 7, 8, and 10: Run the Windows Update Troubleshooter

Windows includes a built-in troubleshooter that may be able to help fix a stuck update. It’s the easiest method to try, so go ahead and run it first. The troubleshooter performs three actions:

1. It shuts down Windows Update Services.
2. It renames the C:\Windows\SoftwareDistribution folder to C:\Windows\SoftwareDistribution.old , essentially clearing the Windows Update download cache so that it can start over.
3. It restarts the Windows Update Services.

This troubleshooter is available on Windows 7, 8, and 10. You’ll find it in the same place on all modern versions of Windows.
