Those who say that are incorrect.

That is correct. 32-bit XP can use up to 4GB. However the 4GB address
space has to be shared with memory used for other devices. So Windows
(all 32-bit versions) can't use that entire 4GB for itself.

How much it can use is around 3GB, but depends on what devices are
installed. It's normally a little more than 3GB. So installing more
than about 3GB of RAM is usually a waste of money.
