Roku launches its apps for Windows Phone 8.1 and Windows 8.1 in 2014. The new Windows 10 PC version lets owners of the company's streaming media devices control them remotely via the app's features. The official Roku blog states:

This is the first time the Roku app will be available to tablet users so be sure to take advantage of controlling your Roku device with a large screen and in landscape mode! Navigating more than 3,000 channels and 300,000 movies and TV episodes available on the Roku platform has never been easier. The Roku app for Windows 10 is a universal Windows app, which means it features Cortana support as well.
