I know this is in the SP2 section but the updates today made my SP1 screwy. I never had a problem with any of the previous updates, even the last one that dinged so many here. after the update and reboot, my wallpaper was gone. no biggie, just chose my image again and it reappeared. the wallpaper disappeared again after a couple of reboots and won't come back now, just a solid black background. then tried launching some metro apps. nothing happens, just a blank colored screen with a large icon of the app, such as mail or calendar and it just sits there. I finally got the metro apps running again, I'm thinking because I was toying around with the screen resolution since I'm having issues with a Google Chrome update today too. luckily nothing major but annoying nonetheless. not happy with this update at all.
