my laptop was screwed after the update. windows explorer crashes
VERY frequently now and most of my programs stopped working even in admin mode.
system restore didn't work and i don't have the information i need for a reinstall.
basically whatever it was killed my system and compromised my gear so i wouldn't want to look up anything sensitive to personal data on your machine. also i noticed the update cant be deleted or hidden or detected after a failed install. even though you can clearly see it listed as a failed update... this is bad.
sorry if this isn't what you wanted to hear. maybe it effects things differently depending on location and computing capabilities. hope for the best and try to restore.
