Xbox Insiders could previously test out the new Avatars through the console itself, but now select Insiders can do the same on Windows 10 through the Avatar editing app.
In a post on Xbox Wire, Brad Rossetti detailed how this will work.
“Avatar Editor on Windows 10
We’ve mentioned before that the Avatar Editor is a Universal Windows Platform application and now we’re ready to start collecting feedback from Windows 10 users! If you’re in the Alpha Skip Ahead, Alpha, or Beta rings on Xbox One, you’ll find a new quest in the Windows 10 version of the Xbox Insider Hub that will tell you how to download and provide feedback for the Avatar Editor on your Windows 10 device. Please note that the Avatar Store will not appear on any version of the Avatar Editor on Windows 10 at this time.”
The latest update for members of the Alpha ring also brought the following fixes:
FIXES:Audio ■ Fixed issue where some audio events caused the console to crash.
My Games and Apps ■ Fixed an issue with the YouTube app failing to launch. It should no longer
crash immediately upon launch.
■ Fixed issues in which some users could not launch or reinstall Netflix.
■ Filtering Groups within collections will no longer display a blank drop down
menu.
