I am at home but I have the problem too.
Besides your mesg I got also the message: "A Patch is preventing the system from starting".
To get back in the normal mode I did the following. (cost me over 20 hours to find out)
Go to the safe mode.
Run as administrator in the commandbox SFC /scannow
In the windows folder there is a folder with WINXS/TEMP/PendingRenames.
Move thesse messages to a folder on an other disk (you have to become owner of this folder and files).
Then reboot from safe mode back to normal mode.
This works for a restart. After a powerdown your are lost again.
switch off windows update. It prevents that you get some other fix like KB937287, or the vista SP1.
If somebody knows a better way?

n.b. I am on a ACER Aspire 7720. 2G
