Horrible, one of those things about windows that boggle my mind.
Start up laptop, it applies an update, making the whole environment slow and annoying. End of the day, shut down the pc and it says it needs to update/install whatever number of things. why do you do this, you idiot OS, i got a train to catch/appointment to be at/etc. then the next day, you start up your pc and it says - finishing applying patches/updates. REALLY? why? who made this stuff up? if this is really needed, then your OS is just faulty by design.
