Doing a repair/install with the XP CD is often the best way to recover the
OS, but it's not always possible because the user doesn't have the media
or
the computer only comes with System Recovery Disks that destroy the user's
data. Although I have a number of versions of XP media I don't know which
will accept the user's license key. How many different types of license
keys are there (full, upgrade, OEM?) and how do you identify the media
they
work with?
