Actually the Intel 386 chip could use 48 bit addressing using the Segment Descriptor Table. Apparently nobody wanted to write the OS to take advantage of it. 4 GB seemed like a huge space then. Plus MS got the guys from DEC who did VMS, which used a flat 32 bit address space, to write NT. It was just easier to let them apply their experience rather than complicating things.

That is not correct. While Windows 7 DVDs do include every possible edition on one disc, they come as either 32-bit or 64-bit. Not both on one disc.

Find "4GB-RAMPatch-Multilingual-12.7.2010.exe" and run it.
That's a hack of unknown origin and while it may work, it runs inside the Windows kernel and with full privileges over the entire system. To trust something like this not to mess up your system is insane... It also violates licensing agreements with Microsoft.
I completely agree. I would rep you Corazon if allowed.
