I have had this issue for a while, but it wasn't terribly important until now. I browsed the forums a bit and noticed ya'll have been able to help several others with the problem.
When I try to update to Service Pack 1 for windows 7 professional x64 I constantly get error 800B0100.
I have tried running the Windows Update readiness tool and Windows automatic troubleshooter linked in the Microsoft support article pertaining to this error, but with no results.
I'm attaching a copy of my checksur log in hopes I can get this issue resolved.
Thanks in advance.
