I beg to differ. I was running Windows Vista Business with just 1 gig of memory. the other gig was on my virtual machine leaving the the remaining 1.5 gigs free. I now have Windows 7 Professional 64 bit and the memory jumps around. I run my adobe programs for work here and like usual, it takes some memory as I work. When I shut them off, there is memory floating around. I honestly think they still have pointer issues. This is frustrating. It doesn't freeze up like Vista, but the memory thing bugs me. 600-800 gigs of memory floats around and Windows 7 decides when it should free it up. I don't know what it is. I mean I've shut off services that I don't need. I thought this was the original problem, but it's not. The processes are all the same each time before and after I shut off my programs. I'm thinking of rolling back to XP, or maybe installing LINUX on this machine. Very frustrating when you need all of your memory for work and your virtual machine.
