Windows 10: Issues with night light turning on and off randomly.

Hello!


I have just recently had a number of issues with night light randomly turning on and off and making my screen darker and yellow toned. I've always used nigh light on my computer (just over a year now) and have never had any previous issues with it. It was scheduled to turn on at 8:30pm and off again at 7am. It always worked fine. Then recently, it turns on when I turn on my laptop and randomly flashes off after a while (+ the length of this time varies too). I have tried a handful of things so far including:


- Turning night light off completely

- Changing the level of yellow tone

- Changing the times of night light

- Updating windows

- Updating the drivers

- Seeing if it makes a difference when it is charging or not, or connected to a second screen


Nothing has made a difference so far and its really getting on my nerves ahaha


Some extra things to know that maybe(?) might impact it??

- I often plug a second screen/projector into my computer

- I changed time zones (UK to Japan) so I'm wondering if for some reason it thinks it's UK time? But like I said, night light turns off randomly after a while.


I'd super appreciate any help or advice! Sorry for the essay and thank you in advance!

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.
