2. Run Windows Update Troubleshooter

Note: If you are using a third-party antivirus program, it’s better to disable or remove them and try updating your PC again. 

4. Perform SFC/Scannow

  • When the System Configuration window comes into view, go to the Startup tab and click “Open Task Manager“.

  • Select each one of the running programs and click Disable.
  • After disabling all of the running applications, close Task Manager, and Restart your PC.

6. Reset Windows Update Components 

Cleaning Software Distribution folder 

Sometimes, this is all about the cache stored inside the Software Distribution folder. To rule out this possibility, just clean this following the below guideline –

  • Start the Run dialog (Win & R), type services.msc, and hit OK.
  • On the next screen, scroll down to Windows Update.
  • Make a right-click on the same and click “Stop” to temporarily disable this service.

  • Press Win & S hotkey and type System Restore in the search field.
  • Click on the top result to launch the System Protection wizard.
  • Tap System Restore button then OK to move further.
