Greetings --
Product Keys are bound to the specific type and language of
CD/license (OEM, Volume, retail, full, or Upgrade) with which they are
purchased. For example, a WinXP Home OEM Product Key won't work for
any retail version of WinXP Home, or for any version of WinXP Pro, and
vice versa. An upgrade's Product Key cannot be used with a full
version CD, and vice versa. An OEM Product Key will not work to
install a retail product. An Italian Product Key will not work with
an English CD. Product Keys and CDs cannot be mixed & matched.
It's an anti-theft mechanism, to ensure that you have a valid
license. It's based upon the rather obvious reasoning that a valid
licenser purchaser/owner would, of course, have both the installation
CD and the matching Product Key in his/her possession, as they
originally came together and there'd be no legitimate reason to
deliberately separate them. It is, however, a little troublesome for
the disorganized or negligent.

If it was an OEM license, you should contact whomever sold you the
PC; although very few manufacturers/vendors keep records of the
Product Keys they've sold, it's worth a try before you have to buy a
new license.
