Windows Media Center Extenders, such as the Microsoft Xbox 360, use network ports to communicate over the network to computers that are running Windows Vista Home Premium or Windows Vista Ultimate. This cumulative update contains updates to Media Center programs that may have been previously configured as "approved" or "allowed" by a third-party firewall. If you use a third-party firewall, you may have to manually update your firewall to let the new versions of these programs access the ports. If you do not perform these firewall updates, you may experience failures when you try to connect the Windows Media Center Extender to the Media Center computer.
