True story... Came home the other day from work and my computer was powered up and staring at me, and I knew instantly that something was wrong because it was booted into Windows 7, which it should never do unless told (I have a dual-boot system config). Hmmm, I wondered..?? First, why was it on anyway, and second, why was it sitting at the Win 7 logon screen? I figured it wise to log in and poke around. Then I remembered that the last thing I had done several days before was to let Windows 8.1 apply updates and shut down on it's own. I had gone to bed and forgotten about it. Bad move!!
