Yep repair installation is the exact thing you need. You won't lose anything on the hdd. The only thing I had to reinstall is Windows media player 11. I clicked on the icon and it would take me to the setup of WMP10, so I just reinstalled 11.

"Naming them would either make it clear that Linux is not infringing at all (which is quite possible, especially if the patents are bad), or would make it possible to avoid infringing by coding around whatever silly thing they claim,"
"So the whole 'We have a list and we're not telling you' should tell you something. Don't you think that if Microsoft actually had some really foolproof patent, they'd just tell us and go, 'nyaah, nyaah, nyaah!'?"
