No this isn't a question for the help room, I happened to come across an article written by a man called Geoff Chappell about memory usage in windows and why you can only access 4GB max in a 32 bit system, click here.
I was under the impression that the max amount of memory was a physical limit on a 32 bit system and to utilise more you needed a 64 bit, well according to this article maybe not.
This is just part of the article he has written,
"That 32-bit editions of Windows Vista are limited to 4GB is not because of any physical or technical constraint on 32-bit operating systems. The 32-bit editions of Windows Vista all contain code for using physical memory above 4GB. Microsoft just doesn’t license you to use that code".
If the article is correct have we all just been conned?
