You will face problem with current "pilot" VDI rollout activating MS Office 2010. Pls see this link - http://terenceluk.blogspot.com/2012/01/problems-activating-microsoft-office.html explaining the solution. You will need to do this in every desktop or the master image. If required, you might also need to deploy KMS. See detail here - http://technet.microsoft.com/en-us/library/ee624357.aspx .
