Knowing Microsoft, this is probably a stupid question, but here goes... Is there any way I can get the W2K upgrade (B2300082), with its $70 rebate (what proof do you send in for the rebate?), if I intend to install it on a clean machine (no NT 4.0). I do have 95, 98, and ME, but doubt that will help. I am very interested in trying W2K at home, as I currently use NT 4.0 at work and soon will be upgraded to W2K there. If I must buy a full version, are there any options to lower the rather exorbitant pricing MS has on it?
