Windows 10: Night light not turning on automatically after Windows 10 1903 update

Windows 10 1903 update has ruined the night light feature. The feature promptly shows that its on at sundown but there is no change in the screen display colors. Turning it on and off also has no effect.

Restarting the laptop fixes this issue but it repeats itself the next day.


I tried to reach out to Microsoft through the built in help feature and they agreed to solve this issue for free. They only restarted the laptop and the feature turned on and they considered it solved.


Anyone else facing this issue? I was looking to get a permanent solution to this problem and restarting it after every sundown is not an option.

1903 version night light not working

Hi Monika,

it is a known issue in 1903

Night light settings do not apply in some cases

Microsoft has identified some scenarios where night light settings may stop working, for example:

Connecting to (or disconnecting from) an external monitor, dock, or projector

Rotating the screen

Updating display drivers or making other display mode changes

Affected platforms:

Client: Windows 10, version 1903

Workaround: If you find that your night light settings have stopped working, try turning the night light on and off, or restart your computer.

Note We recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until this issue has been resolved.

Next steps: We are working on a resolution and will provide an update in an upcoming release.

Windows 10 1903 (may update) Breaks Night Light (built in night light mode)

Hi there,

I have 2 machines (1 was an upgrade install to 1903 the other was a clean install). Both nvidia cards, 1080ti and a 2080 in the other (1 has the latest nvidia drivers the other has the very last version prior to the latest). Both intel 8700k processors.

what is happening: i keep the night light mode always on, and prior to 1903 (when i was using 1809), when i play a game (full screen) the nightlight mode would turn off in game. when i alt tab to windows, night light was enabled. when i jumped back into
a game, it was disabled. no issues.

when i upgraded to 1903 (both the clean install machine and the upgrade), when i have night light on, and go in game and alt tab, the night light remains off in windows, this never happened in 1809.

not limited to games, but in both machines using 1903, sometimes when i start the computer, the night light mode is disabled. trying to turn it on does nothing, and rebooting fixes it. but if happens enough now where i suspect this is not a one off, and
the fact it happens on both my computers, and when i go back to 1809 there are no issues.

i also tried flux, but it did the same thing where it would sometimes when you turn on the computer be off, and no way to enable it without rebooting.

lastly, i noticed when the display goes to sleep (the monitor, not the computer), night light is disabled. You can turn it back on, but the monitor being put to sleep effectlivley disabled night light mode from running on 1903, but not on 1809.

somehow i think this is all connected, something in 1903 with night light mode is not working properly like it did in 1809.

computer stats:

Machine 1 (upgrade to 1903):
