In order to deactivate an Office license you can use the “ospp.vbs” script located in the Office 2010 Installation directory.
This allows for a number of functions, my objective being the deactivation of a activated MAK for Visio & Office 2010.
These are the steps take for this scenario:
CD C:\Program Files\Microsoft Office\Office14
CD C:\Program Files (x86)\Microsoft Office\Office14
(32-bit Office 2010 on a 64-bit OS)
