This may have just fixed it, from the techguy forums:
Go into Windows Services, and stop the Windows Update Service (don't disable it, just stop it).
Control Panel (classic View) Admin Tools>computer management>Services.
Once it opens, scroll down to "Windows Update" double click it and hit the stop button in the window that opens, when it stops, click OK and then close the services window.
Now navigate to this location and delete the folder "SoftwareDistribution"
C:\Windows\SoftwareDistribution
Restart the PC and see if WUP works now.

The registry corruption is quite obvious here, and it is clearly not a SoftwareDistribution problem.
