What is Presence Sensing, and how to use it on Windows 11? Everything you need to know

On Windows 11, you can manage the Presence Sensing settings to improve device security and energy efficiency of your computer, and in this guide, I’ll explain everything you need to know, including the steps to enable or disable its features.

What’s Presence Sensing?

Presence Sensing is a collection of features that Windows 11 (version 23H2 and higher releases) uses to detect your physical presence near the computer. 

If you leave your desk on supported hardware with the feature enabled, the computer can turn off the display automatically. When you approach, the feature can automatically wake up the display again. The system can also detect when you’re not looking at the screen to lower the brightness and then restore the intensity when you look at the screen again. This feature is meant to help you keep your computer more secure, save battery power, and get back to work faster. 

What devices support Presence Sensing?

This feature is only available on some computers since it requires special hardware, such as infrared cameras or radar-based sensors, to sense when a person is near or away from a device.

Usually, you will find this feature on premium devices as well as Copilot+ PCs. Also, the features you can use will depend on the computer’s sensors. If your device has no compatible presence sensors, you won’t find any options in the Settings app.

In this guide, I’ll show you the steps to configure the presence-sensing settings on Windows 11.
