Within my 15 years of PC experience I have never seen something like this.
My Path variable within the Environment Variables is deleted for some reason. And now Windows 7 shows for Windows Explorer. Notepad, calculator and everything Windows related a "not found Icon" and it can't be started either.
I even tried to get System Restore started and it can't start saying missing parameter in Environment variables. I obviously can't get in System variables either to reset the path myself.
Is there a way to fix this or do I have to reinstall Windows for such minor thing?
