Windows 10: Having Problems with Night Light Feature

Recently, my Night Light has been malfunctioning. If I have it on during the night and open my laptop the next morning, my screen is still warm as if the Night Light were still on. However, when I check my settings, the feature is turned off. To fix this, I turn it off and then on again. It's an easy fix, but I would rather not have to do it. What can I do?

:)

 

Why is the Night light feature malfuctioning?

Malfunction of the night light feature is a known bug in the v.1903 feature update. See the information from Microsoft

here. Look for the paragraph that starts "Gamma ramps, color profiles, and
night light settings do not apply in some cases." No fix issued yet and considering how many bigger issues Microsoft has to deal with, my guess is that a fix for night light is lower down on the list.

 

Night Light problems

• Click start and then settings.
• Click system.
• Click Display.
• And you'll find night light there.
• And if u want to change the color click night light settings.

 

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.
