I have just cleaned my HP Compaq nx7300 XP SP2 from virut/sality etcetera, and I got back missing system32-files such as ctfmon.exe, msconfig.exe. So now, I have my language bar up working again and also msconfig.exe works. But still, when I type gpedit.msc in "run", I get prompted to choose a software to open with. So the group policy editor doesn't work. Do I need to do a repair install do you think? How important is gpedit.msc?
