Windows 7 is available to MSDN subscribers since yesterday. So I downloaded the 32 bit version to see if I could use all my RAM available on my laptop. As I expected, after a clean install of Windows 7 (x32), I saw in the control panel only 3 Gigs of RAM usable.
The exact message says that there is actually 4 Gigs of RAM, but only 3 Gigs is usable. Since My laptop has 4 gigs installed and I want to take the benefit of it, I'm going to download the 64 bit version of Windows 7. Exactly the same thing what happened to me with Windows Vista when it came out.
I did not test any compatibility issues concerning VMware Client or VMware Workstation. I'll inform you if I run into a difficulties or so. So stay tuned.
