The development comes after Microsoft announced that it has expanded its partnership with the movie service.
Vista users can also stream Netflix movies on PCs by going to the Netflix site.
The arrangement is part of Microsoft’s plans to develop its Media Center as an online video hub.
Microsoft offers Media Center with the Vista operating system.
By selecting the new Netflix tab in "TV+Movies" Vista users can start streaming films immediately.
They will also be able to search and watch programs from Netflix’s online library of 12,000 movies and TV shows.
Microsoft’s partnership with Netflix began last year when it began offering the movie service’s streaming movies through the Xbox 360 game console.
