  1. Why is the Night light feature malfuctioning?


    I have two very expensive laptops which are now both experiencing identical issues with the Windows 10 Night light feature. The issue is the same; fails to turn on and off when it is supposed (according to it's setting). The time and date is correct on the laptops, the night light is set to turn on and off at certain times. It works mostly, but lately it hardly works. I have found that a restart will reset and correct the issue, but having to constantly do restarts is not how it is supposed to operate. The feature worked correctly initially for several months (both units are about 1 year old) and then it started to act up. I have run a full system scan, I have uninstalled and re-installed my graphics driver and it is current. Still the issue exists. Microsoft needs to apply a fix for this...I see many people are complaining about this. The night light is a very beneficial feature when it functions properly, however, it has now turned out to be a stress-causing feature since it doesn't work right.

  2. 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.
