It happened on two PC's right after installing the newest updates that a blue screen showed up: Your PC couldn't start properly, bla. bla bla...then the options to do a restore, reset, start -up repair etc.. It never happened that a system was being repaired, it seems that it's just a part of the program that doesn't do anything. Should that happen to you, just shut the damn thing down. On one machine I couldn't even shut it down and had to unplug it. All you need to do is a restart and it will work again. If some updates are still to install, please download, install them and then do a restart, before you encounter problems. It usually restarts after 15 %.
