In mid-May, 343 Industries announced Halo 5's Forge mode would be arriving on Windows 10 in the up coming months. During their panel at RTX, attendees and live stream viewers were able to get a first look at how the mode will function, including a completely redesigned user interface and will have interchangeable support with an Xbox One controller.
Another showcased feature at the panel and according to Xbox Wire, "one of the most requested features in Halo 5: Guardians" was the Content Browser. The Browser will be available on both platforms and will help players share as well as search for custom maps, game modes and Forge Object Groups.
The full release for Forge on Windows 10 as well as Content Browser has not been announced.
