System hangs on shut down after power loss during update installation

I had a power loss while installing a windows update about two months ago. Ever since then my system will hang either on logging off or shutting down.
I have tried making a new user (No Help)
it hangs in safe mode also.
I also do not have a list of prior updates in control panel since this problem.
The system works fine other than that.

System is DELL studio xpx 1640 x64
win 7 home premium

thanks in advance...
