Setting up a PC to be used for an important presentation with a projector tomorrow trying to make it as idiot proof as possible (extended display, notes and resources on one screen, presentation on other). All set up ready to go, gave it another run tonight just to make sure it's working fine... windows update. Projector will now only display 640*480 and not 1080p as before.
3 hours of removing updates, changing drivers, trying different external hardware. Microsoft tech support replies back with "reinstall windows". 3 Hours left before this PC is supposed to be shipped out and I don't think I can get away with having a sleep at work today.
