well i installed vista home premium just a couple days ago and until now everything was working fine. today i start it up, do some tweaking, and all of a sudden i can't open up the control panel. i tried to expand it in the start menu but it shows up empty! tried running gpedit.msc but i get a message saying that it is missing (not sure if this is attributable to me having home premium versus business or ultimate).
edit: windows update will not open up either
