Microsoft have released a new build of Windows 10 for Windows Insiders on the dev channel. Build 21364 adds GUI app support on the Windows Subsystem for Linux (WSL) so you can run Linux GUI apps directly from your Windows desktop. More details on Microsoft’s blog post.
UPDATE: Here is my hands on video:
In this build Microsoft have added extra information to Task Manager showing Edge resource types e.g. Tabs, Browser processes (Browser, GPU Process, Crashpad), Utility plugins (Utility: Audio Service Extensions), Dedicated & Service workers etc.
Also in Task Manager is the option to throttle applications and put them in eco mode reducing the CPU consumption of the task. Task Manager also indicates tasks that are running in eco mode.
Here are the know issues and fixes with build 21364:
Changes and Improvements
