How to change your CD Key

[BearCat]

This Q has I been getting many times,
from people who somehow has been able to unregister their legit OfficeXP,
and then has been "forced" to do a re-register, only to find out they have used their keys
one to many time, blacklisting their legit CD keys.


Q : How can I change the CD Key of my Office XP installation ?

Answer :
You can do it by editing the Registry.
Apply this procedure:

• 1 - Locate your valid product CD Key, which is located on the back of the original CD case
• 2 - On the Start menu, click Run.
• 3 - In the Open box, type regedit, and then click OK.
• 4 - In Registry Editor, find the following subkey:
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office.0\Reg istration
  Click the plus sign (+) next to this folder. If you see only one subkey in this folder that has a 32-character {GUID} (globally unique identifier), select that subkey and go to step 5.
  If you see more than one subkey that has a 32-character {GUID}, select each one until you find the one whose DisplayName value (in the right pane) matches your version of Office.
• 5 - For the selected {GUID} subkey, select the ProductID string value in the right pane.
• 6 - On the Edit menu, click Rename.
• 7 - Type
  OldProductID
  and then press ENTER.
• 8 - Repeat this for the subkey called
  DigitalProductID
  and rename it to
  OldDigitalProductID
• 9 - On the Registry menu, click Exit.
• 10 - Start any Office program.
• 11 - When the Microsoft Office XP User Information dialog box appears, type your valid product CD Key (located on the back of the CD case). Follow the instructions on your screen.
  

As allways, make SURE you know what you are doing,
as registry editing can render you computer inoperable.
