I was discussing with someone recently who claimed to be an ex Microsoft
OS developer, and he said Home Edition only supported 2GB RAM. Anything
above 2GB, the Memory Manager would just ignore.

Is this true? Is there any documentation specifically address this
issue for Home Edition?

I found this article http://support.microsoft.com/kb/555223/
At the bottom it says it applies to Home Edition as well, but the
content only mentions Professional version.

It's false. The maximum RAM is the same for both Professional and
Home. It's 4GB.

Wrong. WinXP, whether home or pro edition, can handle up to 4GB of
RAM. It's very likely, however, that your motherboard has a lower
limit.

The 64-bit edition of WinXP can handle something like 128GB of RAM.

"All processes (e.g. application executables) running under 32 bit
Windows gets virtual memory addresses (a Virtual Address Space) going
from 0 to 4,294,967,295 (2*32-1 = 4 GB), no matter how much RAM is
actually installed on the computer."

Perhaps that's why your friend is an "EX Microsoft Developer"

That's perfectly true, but it has nothing to do with how much RAM can
be plugged in. Even in you have only 128MB of physical RAM, each
process will have a virtual address space of 4GB. Of course, if each
of 20 processes tries to allocate and use 4GB, it's not likely to work
too well.

But if you have more than 1 GB RAM, you will not be able to hibernate
your machine.

Correction, SOME machines may SOMETIMES fail to hibernate after having >
1 GB memory installed. It is not always an issue.

Well, according to the experience in my site, MOST OF the machines
will ALLWAYS fail to hibernate after having MORE than 1 GB memory
installed. So, if hibernation is an important feature for you, DON'T
add more than 1 GB of memory to your computer or notebook, unless you
test it exhaustively before.

OK, but that's irrelevant to the question asked, which has to do
with whether Home Edition, as opposed to XP Professional,
supports no more than 2GB.
