Microsoft continues to refine power-saving features in Windows 11. In recent insider builds for Dev and Beta channels, user phantomofearth discovered a hidden "Adaptive Power Saving" feature that automatically enables energy conservation based on current PC tasks, battery level, system load, and other factors. This functionality is linked to the recently introduced "Windows Health and Optimized Experience" service.

Windows Insider Senior Program Manager Brandon LeBlanc confirmed Microsoft is working on this feature. He noted it's currently not functioning properly, which is why no official announcements have been made about its existence.

However, if desired, you can forcibly enable the feature using the ViveTool utility. This works in builds 26120.4441 (Beta) and 26200.5651 (Dev), as well as newer versions.

Installation Guide

1. Download ViVeTool from this link.
2. Extract the downloaded archive to any location on your computer (for example, you can create a ViVeTool folder in your C: drive root directory).
3. Open Command Prompt as Administrator (search for CMD and select "Run as administrator").
4. Navigate to the ViVeTool folder using the command cd /d <folder path>, then press Enter. Example: cd /d "C:\ViVeTool".
5. Enter the command vivetool /enable /id:56401475 and press Enter.
6. Verify the command prompt displays "Successfully set feature configuration".
7. Restart your computer to apply changes.

To disable the feature, use this command:

• vivetool /disable /id:56401475
