Urgent Help!

[InsaneHanz]

I have a big problem on my hands here, something to do with my registry. So, here's the problem:
I can't open any program through normal means, not through Start> All Programs, shortcuts, or Start > Run. My computer can't recognize .exe files pretty much. Every single shortcut has a .lnk at the end of it. I have some system restore points, but I don't know how to access them. Please help!

Does this problem happen in safe mode aswell?

Yes, it also happens in safe mode. I believe something changed my registry.

Ok, I found a few backups of my registry, and I managed to open up regedit.exe. If I were to import one of these back up registry files, would my computer become even more screwed up?
