If you didn’t install it yet, the build 21364 introduced several new features including support for Linux GUI applications on the Windows Subsystem for Linux. The Windows 10 Task Manager has also received some love with a new Eco mode that can throttle process resources for apps that are misbehaving. Task Manager has also been updated to display different Edge components such as tabs, browser processes, utility plugins, and more.
If Linux GUI apps are available for all Dev Channel Insiders who install the build 21364, the Task Manager changes will only roll out to a subset of testers for now. You can check out the full list of new features, bug fixes, and known issues for the build 21364 on this page.
