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


    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
    monitor asus 32inch running at 75hz (non-gsync)
    Machine 2 (clean install to 1903):

    8700k
    32gb ram
    970 pro 512gb
    evga 1080ti hybrid FTW3
    nivida driver 430.39
    monitor lg 31.5inch 144hz g-sync

  3. No Night Light

    Hi allisonb1

    Try these steps

    Option 1. Reset Night Light-related Settings on Windows 10 Fall Creators Update

    If you find the night light in the Action Center or the Settings is greyed out after the Windows 10 Fall Creators Update, you can fix it with the steps below:

    Step 1. Use Windows shortcut keys Win + i to open Settings.

    Step 2. Go to the Privacy menu.

    Step 3. On the left side, choose the Location tab.

    Step 4. Click the Change button under the Location for this device.

    Step 5. Toggle the switch under the Location for this device to ON.

    Step 6. Toggle the switch under the Location service to ON.

    Step 7. Restart the computer.

    Now check the Action Center or the Settings on your Windows 10 Fall Creators Update to see if the night light feature is available.

    Option 2 . Modify Registry to Fix Night Light Not Working on Windows 10 Fall Creators Update

    If the methods above didn't work, you may need to modify the registry to fix the greyed-out night light button or the night light not working issue. Note: Windows Registry is a vital database on Windows OS computer. Any misoperation will cause server system
    problems, such as 100% disk usage issue, blue screen issue, endless reboot, etc. So it's important to backup registry before the changes.

    Now let's kill the night light not working and release the pain:

    Step 1. Use Windows shortcut keys Win + R to launch Run.

    Step 2. Type into regedit.

    Step 3. Hit the Enter key.

    Step 4. Copy and paste the path into the address bar of the Registry Editor: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount

    Step 5. Press the Enter key.

    Step 6. Right-click the key $$windows.data.bluelightreduction.bluelightreductionstate under the DefaultAccount and select the Delete to remove it.

    Step 7. Right-click the key $$windows.data.bluelightreduction.settings and select the Delete.

    Step 8. Restart the computer.

    Then you can go to the Action Center or the Windows Settings. The night light not working issue has been resolved now and the night light button is available.
