Channel 4 is the UK's first mainstream broadcaster to release its on-demand catch-up service, 4oD, on Windows 8, Microsoft's latest operating system.
The app, popular for catching up on shows like Homeland and The Big Bang Theory, has beat the likes of iPlayer and ITV player to launch on the Windows 8 platform.
Sarah Rose, director of commercial and business development at Channel 4 said the new app was part of a "pioneering commercial solution".
"Creative apps such as this that will continue the great momentum and excitement around Windows 8," said Microsoft's Anand Krishnan.
Microsoft recently announced that it has sold 40 million Windows 8 licenses in the first month of its launch, beating its predecessor Windows 7, which sold just over 60 million units in the first 10 weeks of sales in 2009.
The app is now available as a free download from the Windows Store.
