Windows 10: 1903 version night light not working

Hello guys,


after updating to 1903 version, today I've noticed that night light is not working. I need to do a sign out option and then re-sign for night light to work. Does anyone have a solution, or it will be fixed in the next update?


Best regards.

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):

• 8700k
• 32gb ram
• 970 evo 1tb
• nvidia 2080 FE
• nivida driver 425.31

Night light fast startup bug windows 10 version 1903 build 18362.53


Hi there,

I am having the same issue, or a derivation of it. i Have btw the RTM version of 1903, i am not on the insider program or anything. my main issues are night light mode disabling (and not re-enabling) when gaming and then alt tabbing back to windows and when the monitor goes to sleep (not the computer)... more info...
