From time to time, Windows may have a corrupted file store, which houses Windows update information. This may lead to issues with Windows updates being downloaded and/or installed. 


To resolve:


1. Right click Start, click "Terminal - Admin". 
2. In the resulting window, copy and paste this command: 
Dism.exe /online /Cleanup-Image /StartComponentCleanup

And hit enter, let the scan run. 

3. Do the same with this command: 
Dism.exe /online /Cleanup-Image /SPSuperseded

4. Then in the same terminal window, type: sfc /scannow and hit enter, let the scan run and finish. 

5. Then run Disk Cleanup by clicking Start, type: Cleanup -- right click Disk Cleanup and select "Run as Admin" -- opt to clean up/delete all files in the resulting dialog box. 

Once this is done, reboot. 

Run Windows update again and check for issues.
