Removing Office License Key (Legal)

By rdbaird ·
Before I get flamed for hacking, let me explain my situation. We in the IT department here have an image to load our PCs quickly. We have legal licenses for all of our copies of Office XP.

We want to be able to run Office Update on the image PC and then wipe the key off to put the proper license key on each computer, rather than taking 1-2 hours updating every PC (about 300). We have not found a way to do this yet, so any suggestions will be very welcome.

If I need to clarify anything, please post back and I will do my best.

Thank you,

It does not matter that you only have the 1 license key on ALL of those pc's. As per Micro$oft$ licensing requirements, as long as you have valid keys (even if it may be one), but have the required licenses (whether it be a paper license for 10 / 25 / 50 / 100 users or the actual retail software with license), you are just fine the way you are.

Or if you want to anyway, follow these steps:
(For Office XP)
Locate your valid product CD Key, which is located on the back of the original CD case.

On the Start menu, click Run.

In the Open box, type regedit, and then click OK.

In Registry Editor, find the following subkey:


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.

For the selected {GUID} subkey, select the ProductID string value in the right pane.

On the Edit menu, click Rename

Type ( you wanna back it up just in case )


and then press ENTER.

On the Registry menu, click Exit.

Start any Office program.

When the Microsoft Office 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.

Thank you! It worked wonderfully. The only thing is that there is also a Digital ProductID subkey that needs renamed also.
