If you haven't upgraded to a 64-bit operating system, you might want to
soon.

Anyone with more than 4GB of RAM has definitely already done so.

untrue. PAI is still a thing.

Is that anything like PAE? Something that Windows doesn't really support
(supposedly it does, but not for increased RAM).

A real 64-bit OS should still be better.

I used to have a system with 8GB and Windows XP (32-bit). It had some
software to use the extra RAM is a disk. That's one place where it makes
sense to use a software RAMdisk for the swap file. I suppose I'd still
be using it if it hadn't died last summer. I used 64-bit (Win 7) on the
new one.

Some of the 32 bit Windows server OSs support PAE properly and can use
more than 4GB of RAM.

But MS never allowed that on normal end user versions of Windows. I
think it could cause problems for third party drivers or maybe they just
wanted to force us to move to 64 bit sooner.

I think it's the latter.

"... the majority of device drivers today can probably handle
physical addresses above the 4GB line. However, 32-bit Windows
will continue to ignore memory above it because there is still
some difficult to measure risk"

Back in the day, there were discussions about "bounce buffers"
and PCI cards with "dual address generators". That's where
the PCI bus transaction places two 32 bit address words on the
bus, so that 64-bit address locations can be selected. That would be
if a PCI card wanted to DMA into main memory perhaps, and the
address had to be above what a 32 bit address could handle.
