You will be able to search the entire Netflix library right from Windows Media Center, and manage both your Instant and DVD Queues. Windows Media Center will also take advantage of Netflixs "recommended" categories.
You can also use your Windows Media Center remote to navigate the player controls and queues for Netflix in Windows Media Center too.
Netflix in Windows Media Center is powered by Silverlight.
If you also have an Xbox LIVE Gold membership and have been streaming Netflix movies and TV episodes to your Xbox 360, this offering will work for you as well.
Netflix in Windows Media Center currently will work only for Windows Vista Home Premium and Ultimate users.
