Is there a patch or fix available for that. I had seen Microsoft provide hotfix for number of Windows issue, but they do not offer any hotfix to restore Explorer.exe errors. I had searched Microsoft site for hours but yet there is nothing listed. The answer that worked for me Repair setup. Repair setup does not wipe your Windows settings it just restore the system files. You will need Windows XP bootable disc for that. It will try to restore all the files and without removing any installed software. But still take a backup before doing this.
