Task Manager has added a new feature “Eco mode” to identify & assist you to throttle system resources used by an app. This feature is helpful when you notice an app consuming high resources and would like to limit its resources so that the system gives priority to other which will lead to faster foreground responsiveness and better energy efficiency. Eco mode will lower process priority and improve power efficiency for the enabled app

Prerequisites: This feature is available on 21364+ on co_prerelease

Steps:

1. Open Task Manager.
2. Click on Processes.
3. Right click on a child process or individual process
4. Click on “Eco mode” in the context menu to apply throttling.
5. The status column in the Processes tab should show Eco mode for the process

You can follow the same process on the Details tab. After you apply Eco mode you should see “Low” for Base priority and “Enabled” for Power throttling column.

FAQ:

Why is “Eco mode” grey out?

If “Eco mode” is greyed out, then it’s a parent/group process. Expand the process tree to apply Eco mode on one of its child processes. We do plan on bringing Eco mode to the parent processes.

Microsoft Edge/Google Chrome are showing “Eco mode” but I did not apply it.

Both Edge & Chrome are experimenting with lowering base priority and applying power efficiency APIs to improve performance which is similar to what Task Manager is doing to identify Eco efficient apps. You may see other apps with “Eco mode” if they adapt to similar techniques to improve performance.
