Pro does it fairly often. I have 2 notebooks and a desktop that experience it. It's possible to disable it via group policy as far as I know.

The annoying thing is that the advance warning is gone, probably some default setting says that it will reboot sometime, but I very rarely get notified that updates are pending and that today/tomorrow I'll get a forced reboot. It just does it when I lock/close/sleep the laptop/desktop.
