How to set up synchronization between the player and your computer in Windows Media Player 10?
Start Windows Media Player, and then connect the player to your computer.
If you have not set up synchronization between your computer and the player, the Device Setup Wizard starts.
In the Device Setup Wizard, click either Automatic or Manual. Automatic is selected by default if the player's storage capacity is greater than 512 megabytes (MB). If your device has less capacity, Manual is selected.
The wizard closes and the player's Sync feature is displayed.
