Windows Media Player is updated from time to time with new features and performance enhancements. You can let the Player check for updates automatically on the interval of your choice or you can check for updates manually. To update the Player, you must be logged on to your computer as an administrator or a member of the Administrators group, and you must be connected to the Internet.
Click the Help menu, and then click Check for Updates.
If the Help menu is not visible, show the Classic Menus.
Click the arrow below the Now Playing tab, and then click More Options.
On the Player tab, under Check for updates, click the interval option that you want.
