Have you ever returned to your computer only to find it having restarted, and all of your data gone? For a myriad of reasons, I keep my computers running continuously for a long time at a time. This makes this insistence on a reboot not only annoying, but in its extremes, it can actually make me lose work. To prevent this, I have disabled the auto-reboot, and I am no longer annoyed with repeated requests for reboots.
