    No it is only a cosmetic change to end the confusion when folks saw that the OS didn't seem to recognize that there was 4 gb installed. Because the OS has to reserve a portion of the available address space for software, there will NEVER be a 32bit OS that will dierctly utilize all of the 4gb of memory.

    there is still a limit, because the ABSOLUTE MAX ANY 32-bit OS can support is 2^32 bytes (4,294,967,296 bytes (4GB)), but some of that memory will be used for the system, and is not accessable (hence the OS normally shows 3GB or 3.5GB).

    And if you have a seperate GPU with its own VRAM, then that will also take up some of the 4GB limit...
