When I was using my company laptop in office, suddenly there was a error msg "pardlg.dll could not be found" popped up, then the system was "locked" and went for reboot automatically. After that I found out that some Windows Update automatically began. Finally when it was over and I logged in again, all my unsaved work were gone! Such things never happened to this XP + SP2 book before. Anyone got any idea what this "pardlg.dll" was meant for?
