Number 2 is incorrect 32 os can use all of the 4 gigs of memory if yeh dont see all 4 gigs its because its being used go figure.
That's also false.

Well, there are exceptions, but not that matter for our purposes (badly implemented address extension tables, zero video memory). It's 64-bit if you want to use more than 4GB minus your video RAM.

32-bit Vista has been patched to "lie" and report the installed capacity in place of the usable capacity. This may be part of what misled you?
