It will replace all system files. I think it will return you to the service pack level of the install CD, not sure on that. If you google "repair install XP" you should find lots of info.

Good luck.

I second this method. It is the most reliable way to fix an unknown Windows OS problem, especially stemming from a corrupted file. The linux junkies can do what they want, but this is a nice tool from Microsoft that I've found easy to use and invaluable.
Once you're back up and running, I suggest you do all the regular maintenance (scandisk, defrag, antivirus, antimalware, registry check, and uninstall programs you don't use.)
