Even though this is not a mobility blog I still wanted to update you guys that there a is update for the Windows Mobile Device Center on Vista only! It seems that some people had troubles synching and what not. I am using a WM6 device myself and did not encounter any problems, but I did upgrade my WMDC.
You can find the 32-bit download here http://www.microsoft.com/downloads/details.aspx?familyid=46f72df1-e46a-4a5f-a791-09f07aaa1914&displaylang=en&tm and the 64-bit here http://www.microsoft.com/downloads/details.aspx?familyid=4f68eb56-7825-43b2-ac89-2030ed98ed95&displaylang=en&tm
This update does not only fix the synchronization issues but also adds other key improvements and new features to support Windows Mobile 6 devices.
