Windows 7 x64 service pack 1 failed!!
Posted on 2011-03-11
I have 15 pcs with Windows 7 and the service pack tried to install 2 days ago from our WSUS server. It was successful for only 2 pcs. The others got an error and was unable to boot. I then renamed files under \windows\system32\config\ using the recovery console (command promt) and the system booted back.
Since that time, I see "Windows 7 Service Pack KB976932) under control panel, installed updates. When I right click "my computer", SP1 doesn't show up... I feel that SP1 is not really installed.
I then installed the readiness tool and it run's perfectly (feb 2011 version).
After, I tried to install SP1 again (from manual download) and I get this error message: 80070BC9 in the update history. The system always says that I need to restart the computer before applying the update...
I really don't know what to do.
I want to install SP1 but not to reinstall all PCs from scratch.
Please help me!
