This tutorial will show you how to turn on or off Schedule night light for your account in Windows 11.
Your display emits blue light—the kind of light you see during the day—which can keep you up at night. To help you get to sleep, turn on the night light and your display will show warmer colors at night that are easier on your eyes.
You can turn on Schedule night light. Then, either select Sunset to sunrise, or select Set hours and enter custom times for the night light to automatically turn on and off.
Night Light settings are stored in the registry keys below for the current user.
Open Settings (Win+I).
Click/tap on System on the left side, and click/tap on Display on the right side. (see screenshot below)
Click/tap on Night light on the right side under Brightness & color. (see screenshot below)
Do step 5 (on) or step 6 (off) below for what you want.
Sunset to sunrise requires Location services to be turned on at Settings > Privacy & security > Location.
This is the default setting.
You can now close Settings if you like.
