To develop WPD drivers for Vista SP1:

- Build them using the Vista WDK (version 6000) or from the Longhorn Server Beta 3 WDK build environments.   

- WPD drivers built using Longhorn Server WDK Beta 3 will not run on Vista RTM or Windows XP, this is because the version 1.7 WDF Co-installer shipped in the Beta 3 release does not support downlevel operating systems (Vista RTM, XP, Server 2003).  

 

To develop WPD drivers for Vista RTM:

- Build them from the Vista WDK (version 6000) 

- The drivers can run on Windows XP with INF changes and Windows Media Player 11 or Format SDK Redistributable 11 installed
