I own one Windows 7 Pro OEM license and one Windows 7 Home OEM license.
The Pro license is currently in use on a computer that doesn't take
advantage of its advantages (specifically its RAM limit of 192 GB. My
new build-in-progress has the Home license installed but not yet
registered. I'd like to up the RAM on the new build to 32 GB, but I
know that Home is limited to 16 GB.

Is it be possible to de-register the Pro license from the old computer
and install it on the new build? I'd install Home fresh on the old
computer, of course. The hardware on the two computers is completely
different.

Nothing much musical, when MSFT deliberately doesn't define a score.

The ambiguities, apparently, can be something of a computer
philosopher's Rabbit Hole. For instance, notice how the links diverge
in this article. . .
http://www.makeuseof.com/tag/how-to-...dware-upgrade/
.. . .into, again apparently, how you choose to define your upgrade, as
opposed a significance MSFT imposes upon interpreting OEM and Retail
licensing agreements.

Links which will delve deeper into some discrepancies, and
methodologies permitted, between MSFT and you.

Foremost qualifying an OEM status, which is skewed against you, from
how a Retail presentment is by intent to attract customers to spend
more, for both to be within yet allowable limits, indeed, for which
MSFT [dis]qualifies beyond an update, requiring a user to repurchase,
in entirely, the OS from Square One.

Assume to prepare for the worse. As have others, for consequent
resources, (alluded to in the above links), obviously no less apparent
in your predicament, which may be more or less a matter of shades to a
gray legal area, you're nonetheless more or less given wisely, or
discreetly, to engage.

Will a disgruntled employee or observer run to report you to an MSFT
800-hotline, for illegal activity, for droves of Microsoft lawyers to
descend upon you -- having not updated, say, hardware on your
one-hundred Windows 7 office machines? Depending on a method and
resources available, without direct MSFT oversight, I'll hazard you're
small-fry, inconsequent to a grander scheme of how things actually
work as enforceable, legally binding policies, to the Greater
Copyrightists of the U.S. of A. Self-writs, subsection articles filed
under Alice's Hole, anyway, are now by in large written and bound to
Windows 10 telemetric corporate policing activities;. . .Windows 7,
naaaghhh ... less a solution to the MSFT problem, these days, and just
wall graffiti, where you're on "borrowed time" and limited support.
