I got an update stuck in Windows Update. At every system start and shutdown it started the usual annoying stuff about not stopping the computer and preparing updates and whatever goes on in the background. Now I have 2. (KB2732487 and KB2719857)
After a little googling I found that I should use Microsoft Fixit and everything will be fine again. Well, I did. It said that it fixed everything. And I still have the same problem. What else could I try to fix this? (I don't really want to reinstall the system or go to a restore point which was created months ago.)
EDIT:
The log file says 2012-09-13 16:13:43:380 2264 1620 Handler Completed install of CBS update with type=3, requiresReboot=1, installerError=0, hr=0x0
