So far, even Windows Vista Beta 2 hadn't had the new Mobile Device Center included but you had to install ActiveSync instead to got your Windows Mobile devices synced. Now, Microsoft released an update for Windows Vista which includes the Windows Mobile Device Center, which is also the new name for ActiveSync in Microsoft Windows Vista and which will completely replace ActiveSync. It provides overall device management features for your Windows Mobile-based devices in Windows Vista, including Smartphones and Pocket PCs. All of the features previously available in ActiveSync are available in Windows Vista, including synchronization and setting up your partnership. However, most of the user interface has changed in an effort to enhance your ability to easily and intuitively find device-related tasks and improve the overall usability of those tasks.
Please note that still only a portion of Windows Mobile Device Center is included in this release of Windows Vista. This primarily includes core device connectivity components, which allows the operating system to recognize that a Windows Mobile-based device has connected and load the appropriate device drivers loaded and services. The Windows Mobile Device Center application then enables some new functionalities like PIM, photo, video and audio sync, as well as the ability to browse the contents of your device, use desktop PassThrough to sync with Microsoft Exchange and change some general computer and connection settings.
The new version is available via Windows (Vista) Update now.
