One of my Windows 2008 R1 servers suddenly refuses to update. The process seems to be taking forever (or rather stuck) even for searching for updates.
Luckily the solution for me is simple:
- At the Task Manager, search for “wuauserv” process (in Window 10, search for Windows Update) and stop the process.
- Delete all of the files found under C:\Windows\SoftwareDistribution directory
- Run Windows Update (issue should be resolved)
