Change Office 2010 product key from MAK to KMS on thousands of XP machines.

Question

We recently purchased a campus agreement through Microsoft. At the same time I have been building a new image to re-image all computers over the summer break (school district). We were given a license to use to activate Office 2010. I used this in the image and it turns out that it's a MAK key with limited uses (which we've already surpassed). We are still waiting on Microsoft to supply our KMS key for this product but I have been trying to find out how to convert the machines that have already been imaged without re-imaging or reinstalling office. There will be thousands of machines so I need to script this somehow or push it through SCCM. I've read about slmgr & vamt, but neither of these work on XP. Please help!

The easiest way to script this would likely be using the ospp.vbs /inpkey command. Even if your remote machines are WinXP, you just need to ensure remote WMI works correctly:

Here is the list of KMS client keys. Choose the correct key based on your product, and install this key. This key will change your Office installations to look for a KMS host to activate with.

To give yourself more time to set up the KMS host, you can run rearm on your client machines after you change to the KMS client key. This will give you 25 days where users will not see notification dialogs to activate:
