My computer is slowing to a crawl once again

My computer is slowing down to a crawl once again and it is because Windows update is running every five minutes.  Or maybe I should title this 'Microsoft is trying to kill Windows XP' and how to fight back.  The first thing to do is to turn off auto updates and free up about 400 to 500 MEGS of memory.  What, are these people so crazy as to think that a monthly update requires 1/2 a gig of memory almost all of the time????

First to an alternate control delete to see if windows update is the problem. In the picture above it and its associated service host are taking 400 megs of memory.  Then do a start run services.msc and turn off automatic updates.
