Where Are Windows Night Light Settings Stored?
Windows Night Light settings location, schedule control and the blue light filter behind it.
Last updated
Night Light tints the display warmer to cut blue light in the evening. Settings live under Display with a strength slider and a sunset to sunrise schedule. It needs no files to manage.
The schedule can follow local sunset with location on, or fixed hours you set. Some color sensitive work wants it paused. Toggle it from the quick settings panel for one off evenings.
Where Windows stores this, by platform
Settings > Display > Night Light
Strength slider and schedule live here. Use Location for sunset timing or set custom hours. Quick Settings toggles it without opening the full page.
Frequently asked questions
Why did Night Light stop turning on?
Open the same Night Light settings page and check the schedule and strength slider. Turn on scheduling so sunset to sunrise runs automatically. Location services improve the timing.
Does Night Light replace display calibration?
No. The filter shifts color temperature in software. Calibration profiles and HDR settings stay separate. Strength is personal, so nudge the slider over a few nights.
