2 ways to address this that I’ve seen.

The first requires you open a command line with Administrator Priveleges and type in the following:

1. net stop wuauserv
2. rename c:\windows\SoftwareDistribution softwaredistribution.old
3. net start wuauserv

The second is the open Services.msc and stop the Windows Update service (same as using the commands above, use this if that doesn’t work).

At a Run lines, type in services.msc

1. Stop Windows Update service
2. Browse to c:\windows\SoftwareDistribution and rename the folder to softwaredistribution.old
3. Start Windows Update service
