1.Try to go into safe mode by perssing F8 right after turning on the computer. Login as usual and do a system restore to an erlier time that patch was applied.
2.The first thing I always recommend is using the sfc/ scannow. Click on Start/ run and type "sfc/ scannow" without quotes. Of course you are gonna tell me that Windows Explorer is doing the error thing. Right after you boot up windows open the Task Manager by pressing Ctrol+Alt+Del in the keyboard, or by right clicking the taskbar and selecting TASK MANAGER.
Once there click on Processes Tab and look for explorer.exe, highlight it and click on end process. You will see that the only open Windows will be the Task Manager and Windows Explorer error should not bother you during that time. So now you should be able to run the sfc/ scannow. Have your XP CD handy cos' it will probably ask you for it in case Windows would need to replace a damaged file. When finished just restart the computer using the task manager...
Hope this help
