Media center is built into the OS. You cannot have it seperatly. You can buy programs that have the same functionality as Media Center, and use them with XP pro though.

It is a full OEM version, not an upgrade.

To use any of the good 'Media Center' features you should have a TV tuner card.

Media center is Windows XP Pro with "Media Center" built in, with some of the pro features disabled like joining a domain etc, stuff you will probably never use anyways. If you have problems with XP you will probably have problems with Media Center.

The first 2 reviewers on newegg sound like Idiots, FYI, Media center has more 'pre installed' drivers then XP Pro. It sounds like they are incapable of installing an OS. "The CD is missing explorer files", rofl.

ALWAYS DO A FRESH INSTALL.
