Windows could not connect to the Group Policy Client service (non-Admin accounts)

So, after having done an in-place upgrade from Windows 7 Prof to Windows 7 Ultimate, I could no longer log in with my unelevated-user-account. My Admin account worked fine.

I was presented with this horrific screen:

GPC-Unable-to-Login

The answer for me was a missing registry key and some configuration--adapted from the source article below. In my case, GPSvcGroup was missing in the Svchost key and then the actual key was missing too with the 2 registry values needed.

Below is a summary of the SVCHOST tree changes needed:


      HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SVCHOST
          GPSvcGroup REG_MULTI_SZ GPSvc
          GPSvcGroup (Key)

                AuthenticationCapabilities DWORD 0x3020 (12320)

                CoInitializeSecurityParam  DWORD 1
