Apparently KB3159706 breaks WSUS for some of my customers. I’ve had a few calls where they say that WSUS doesn’t work any longer or that the Software Update Point in Configuration Manager is generating errors.
Well, the fix for this is quite simple. (It’s also stated in the KB-article)
Some manual steps are necessary for the installation to complete:
Open a CMD as admin on the server and run the following command:
“C:\Program Files\Update Services\Tools\wsusutil.exe” postinstall /servicing
Verify that HTTP Activation is enabled for the .Net 4.5 Framework feature
Restart the WSUS service
After this has been completed, everything should be back to normal.
