over the last 2 days, 4 of my windows 7 computers have stopped booting properly. as stated above, some boot into a temporary profile, others boot to a locked profile screen. some are windows 7 home some are pro. i have also seen another 4 or 5 computers with the same problem. All computers are current in their updates, and it appears that a recent windows update has caused this problem. I am able to restore them to a previous date and some work fine afterwards, but some will repeat the error occasionally. i have run combofix and glary utilities on them but are not confident that they will continue to boot.
