work computers

does everyone's work computer take at minimum 20mins to boot up into a workable state or is that just here? TODAY it took over an hour, at the conclusion of the 1st hour windows told me it was finished installing updates (and being a total resource hog) and that i had to reboot, so i did, when it came back it was fine after 15mins of i dont know what.. but its working... albeit the windows updates icon went nearly immediately from green to yellow, so did it not install correctly or did it just not install everything so this will happen the next time i reboot, good thing i only reboot over the weekends.. LORD!
