1 Important thing very important??????????.....
You partition hard drive and you instal 2 windows, 1 windows you install no microsoft updates as you need a bare windows.
Some stuff download if for video work but for render work, 3d work, video work, a basic windows will allow you to have more system free.
As on my other new base unit im installing a second windows which i will use for internet gaming and ther stuff, but main partition will be basic so i can do lot's work with no memory hangups.
And if you use other partition for poser ect remember to take ya cable lead out from modem or set top box.
A bare windows makes all the difference, for using applications that use lot's of system propertie's.
