I made a simple batch file to help fix Windows Update errors on our Windows Servers at work (both 2003 and 2008 / R2). It is based on some advice for various Windows Update errors that were on the internal knowledge base, which was no doubt gathered from information online somewhere. It performs a series of steps, saving a great deal of time over having to perform them manually.
Word of warning: The script will attempt to copy pending.xml before deleting it. If it cannot copy it it will delete it. Personally I have never been able to copy the file; most likely because I have not rebooted the server after taking ownership and granting myself full permissions to the file. I should add however that in all my use of this script I have not suffered any problems when deleting the file. Windows Update will recreate it the next time you/the computer downloads required updates.
