Setting Up the Windows Mobile Device Center in Vista

1. When you plug your Windows Mobile device into a PC running Vista for the first time, you should be notified the device drivers are being installed, and eventually a window similar to the screenshot below will pop up. Just close this window if it appears.

3. When opened, you can set a couple (not many) of the Windows Mobile device connection settings. Make sure at least one of the connection methods is enabled. If you’re not presented with the window below (Connection Settings), scroll down and see if the window similar to the one in step 6 is displayed. If it is, that means you have the full Windows Mobile Device Center already installed, and can continue on at step 6.

4. In order to sync your email, notes and calendar from Outlook, you’ll want to download Windows Mobile Device Center 6.1 for Windows Vista. Save the file to your desktop (or any folder) and once the download has completed, run it.
5. Follow the few installation steps (which mostly consist of clicking ‘Next’ a few times).
6. Now go back to the Control Panel and double-click on the Windows Mobile Device Center. Make sure your Windows Mobile device is plugged in and the status is set to Connected. Click the Set up your device button.
