the other night i was doing some automatic updates on my computer..i have win xp pro service pack 2, and after the updates had finished i restarted my computer like normal and when it booted back up and i logged in my background loaded up but no desktop icons or explorer.exe. I can open up task manager, but i cant manually open up any programs at all except for regedit. I'm not sure what is going on and could really use some help...i dont know if i can copy the explorer.exe file from a friends computer and put it on my computer to see if that fixes the problem or not...someone please help me asap!!
