  1. Night light not working.


    Hello,

    After I reinstalled my win10 this June. I noticed that Night Light is not working properly.


    Night light is not working on the first startup but when I restart my PC, it will work. this is weird.


    I already tried some fixes but none of them works.

    - Reinstalling Graphics Card (clean install).

    - Reinstalling Generic PnP monitor.

    - sfc /scannow


    I don't know what happened to my computer after I reinstalled Win10. Some apps is crashing even I reset/reinstall my pc a couple of times.

    Is it my PC or 1903 Update? Please help!


    Thanks in advance.

    :)

  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.

  3. Night Light Setting and Third Monitor.

    Hi Reagan,

    We would like to ask you some questions in order assist you properly:

    • Did Night light work previously on all three monitors?
    • Have you made any recent changes to your PC?
    • Are you getting an error message on the third monitor regarding Night light?
    • Is the third monitor being detected by your PC?
    • What troubleshooting steps have you performed so far?

    While waiting for your response, we suggest that you try to connect your third monitor to what you are using on the 2 working monitors to see if it is only a loose connection issue.

    Regards.
