It will ask you to enter your Office 2010 KMS Volume License Key
Once entered you are ready to go - note, you need as least 5 clients try to activate Office 2010 before those clients are able to activate via KMS
From the client, you can either wait for Office 2010 to activate itself via KMS or you can force it using:
cscript ospp.vbs /act
note: ospp.vbs is located in your office14 installation folder
If you have already activated your Office using the MAK key, you can change that activation to KMS by entering KMS Client key:
cscript ospp.vbs /inpkey:
The KMS Client key can be found from:
