I have 2 laptops and a desktop and would like to know what is the difference
between windows XP OEM and windows XP as I want to upgrade all 3 with the
same disk. I ask because someone mentioned that you can only use one of the
2 disks on 1 machine only but I don't know. Can someone explain to me the
difference.
Thanks

You need to purchase a separate WinXP license for each computer on
which you install it. (As long as you have multiple identical licenses,
it doesn't matter if you use the same CD for the installations, as long
as you use a different license each time.)
Just as it has *always* been with *all* Microsoft operating
systems, it's necessary (to be in compliance with both the EULA and U.S.
copyright law
http://www4.law.cornell.edu/uscode/17/117.html), if not
technically) to purchase one WinXP license for each computer on which it
is installed. (Consult an attorney versed in copyright law to determine
final applicability in your locale.) The only way in which WinXP
licensing differs from that of earlier versions of Windows is that
Microsoft has finally added a copy protection and anti-theft mechanism,
Product Activation, to prevent (or at least make more difficult)
multiple installations using a single license.
One can buy additional licenses, assuming one already has a retail
license. Naturally, Microsoft cannot sell additional OEM licenses. Be
aware, however, that you'll probably pay more this way than you would if
you were to buy a second copy of WinXP from a discount retailer;
Microsoft will only offer you a 15% discount off their MSRP.

1) OEM versions must be sold with a piece of non-peripheral
hardware (normally a motherboard or hard drive, if not an entire PC,
although Microsoft has greatly relaxed the hardware criteria for WinXP)
and are _permanently_ bound to the first PC on which they are installed.
An OEM license, once installed, is not legally transferable to another
computer under any circumstances. This is the main reason some people
avoid OEM versions; if the PC dies or is otherwise disposed of (even
stolen), you cannot re-use your OEM license on a new PC. The only
legitimate way to transfer the ownership of an OEM license is to
transfer ownership of the entire PC.
2) Microsoft provides no free support for OEM versions. If you
have any problems that require outside assistance, your only recourse is
to contact the manufacturer/builder of the PC or the vendor of the OEM
license. This would include such issues as lost a Product Key or
replacing damaged installation media. (Microsoft does make allowances
for those instances when you can prove that the OEM has gone out of
business.) This doesn't mean that you can't download patches and
service packs from Microsoft -- just no free telephone or email support
for problems with the OS.
3) An OEM CD cannot be used to perform an upgrade of an earlier
OS, as it was designed to be installed _only_ upon an empty hard drive.
It can still be used to perform a repair installation (a.k.a. an
in-place upgrade) of an existing WinXP installation.
4) If the OEM CD was designed by a specific manufacturer, such as
eMachines, Sony, Dell, Gateway, etc., it will most likely only install
on the same brand of PC, as an additional anti-piracy feature. Further,
such CDs are severely customized to contain only the minimum of device
drivers, and a lot of extra nonsense, that the manufacturer feels
necessary for the specific model of PC for which the CD was designed. To
be honest, such CDs should _not_ be available on the open market; but,
if you're shopping someplace on-line like eBay, swap meets, or computer
fairs, there's often no telling what you're buying until it's too late.
The "generic" OEM CDs, such as are manufactured by Microsoft and sold
to small systems builders, don't have this particular problem, though,
and are pretty much the same as their retail counterparts, apart from
the licensing, support, and upgrading restrictions.
