Also the part about upgrading will change come Vista. With Vista you
will need to have a validated copy of the OS you are upgrading from
already installed so we should really compare Apples to Apples vs Apples
to Oranges here (OEM vs Retail Full rather than OEM vs Retail Upgrade).
OEM = Original Equipment Manufacturer. Designed to be pre-installed on
a computer. License is non-transferrable except in the event that the
motherboard requires replacement. Can only do a clean installation and
does not require a previous os. Typically costs about half of the price
of the Retail Full copy so tends to be a feasible alternative.
Retail Full = A regular off the shelf product. Can do both and upgrade
and clean install. Can be installed on one machine at a time. This
license is transferable between machines as long as it is removed from
the other machine. You end up paying the full expense here. $199 for
Home; $299 for Pro
Retail Upgrade = A regular off the shelf product. Can only do upgrades.
Clean installs are possible when presented with a cd for the version
you are upgrading from (XP and older only) Can be installed on one
machine at a time. This license is transferable between machines
however the license that you were upgrading from should be as well.
With XP and prior versions it was sufficient to present the CD to the
installer to have it continue with a clean install. Vista will require
the OS that you are upgrading from to be already installed on the
machine before doing so. Certain scenarios will however require a clean
install anyways so one is possible on Vista as long as the OS is
installed already. When upgrading from XP the copy must be activated
and validated.
