So after what seems like an age on Beta Microsoft took the Mobile Device Center to RTM... If your on Vista and you have already got it running best you use the “Uninstall or Change a Program” control panel and select “Windows Mobile Device Center” and “Windows Mobile Device Center Driver Update” from the program list and click “Uninstall”
Only good for Vista so I guess it's time for you to upgrade all that hardware and buy a new copy eh! :)
