Just need to give up half a day of your life. ;)
That happened with my Moms Computer 2nd time starting it up after my Bro built it, "Well

(actual word against TOS so insert cursing smiley)." I said and left the room. Mom "Did you shut it down?" Me "It will after updates." That was in the morning, about mid afternoon it finished. Moms used the computer all of 3 times for a few minutes since, and just recently the HD failed, it's an old IDE one anyway. Said computer was built a year ago.
