I just assembled a new system and installed a ghost drive of my present XP
OS just to get things up and running. I know I have to buy more hardware and
SW for this new system and plan to remove the configuration I have now but
just what happens if I decide to reactivate and use this OS in my new
system. Will my old OS some how become unusable or detected as a clone? I am
referring to and OEM version of XP to begin with and isn't that version non
transferable? Could someone please explain just how this is supposed to
work.
How it's supposed to work is you either uninstall it from
the other system first, or don't install on the new one at
all. The distinction of running it on more than one system
is not one of "are you using it for what you want to do with
it for everyday fully setup uses", it is one of "it is
running in any way, shape or form".
You old OS will not become automatically invalididated to
run BUT you can't update it anymore. I was about to write
that it will be illegal to keep using on it on the original
system but that is incorrect, it is still legal on that
system but not on the new one. I'm not trying to be
Microsoft's Police Force here, just telling you what their
license "usually" disallows.
You can't just buy a retail XP and use the license to run
the OEM-transferred-over installation either, the necessary
license key won't work and you won't have a unique product
ID. You can't just "decide to use it for new system",
legally, and you will probably have to call them to get it
(try to) activated. AT that point, unless you conceal that
it's an OEM version for another system, they will not
activate you. If you did conceal that information, you are
then more actively breaking their EULA (though technically
you had already done so).
So, how it's supposed to work is that you can't transfer
over the OEM installation at all. MS has decided that they
will make customers go through the entire reinstallation
process again if windows isn't exact same version
(variation, including OEM vs Corp vs Retail, Home or Pro).
There might be ways around that, things technically possible
but legally questionable. You're on your own if you go that
route.
