Before you can use Windows Media Center, you need to make sure that you have it installed on your computer. It is included in Windows XP Media Center Edition, Windows Vista Home Premium and Ultimate editions, and Windows 7 Home Premium, Ultimate, Professional, and Enterprise editions.
It is easy to find out if you have Windows Media Center on your computer. Click Start and scan the Start Menu. If Windows Media Center is listed, click on it to launch the program. If you do not see it there, dig a little deeper. In Windows XP, look through your list of Programs. In Windows Vista or Windows 7, type media into the Instant Search box at the bottom of the Start Menu. If you have Windows Media Center, it will appear in the list of results under Programs. Click on it to launch and begin using WMC.
The first time you start it, you will need to set up Windows Media Center. You can use the Express Setup option to get started and jump right in, or you can select the Custom Setup option for more control over your features and settings.
