Hey there, I ask the question a few days ago about upgrading my daw from xp professional to windows7 and received info from DJ X as well as Bill. However, I didn't see Bill's post until after I'd already ordered the windows7 home premium 64 bit online. When attempting to look at my specs to determine how much memory I had I did the following: I typed msinfo32 in the run box and looked at the specks presented there. It reported a little over 4 gigs of memory and so I placed the order. Then I saw Bills message which sent me in to the system properties where there was reported 3.25 gigs of ram! Which, is correct? Do I need to return the windows7 home premium 64 bit? Thanks
