I have WSUS installed on a Windows Server 2012 Standard instance. At the weekend I have installed various updates, including KB3159706.
Once KB3159706 installed the WSUS console will not run despite both the WSUS Service and Windows Internal Database services running. It keeps reporting the error that the SQL server may not be running, which is not the case.
The fault lies with update KB3159706, and there are two options
Solution 1 (Preferred):
Open an elevated command prompt and type
“C:\Program Files\Update Services\Tools\wsusutil.exe” postinstall /servicing
Wait 1-2 minutes for it to complete…
Enable HTTP Activation under .NET Framework 4.5 Features (I did this in PowerShell or use the Server Manager GUI)
Finally, restart the WSUS Service
get-service WsusService | Restart-Service
The WSUS console should now launch successfully.
Solution 2 (less secure):
You can simply uninstall this update from the Control Panel (Control Panel > All Control Panel Items > Programs and Features > Installed Updates and search for this update, right-click and select uninstall).
