Windows 10: Night light not working in Windows 10 Latest update

Hi, i can't use the night light feature in Widows 10, i have tried several solutions, but the solution that i couldn't do was deleting 2 values in the registry editor, when i go to the registry editor the 2 values... aren't just there! i've updated windows 10 to the latest version and i'm using the most recent graphics card driver. My best guess is that i have disabled some services because my pc has only 6GB Of ram and i want to use the 4 free GB For my apps, i probably disabled a service that has to do with the night light... please help.

:)

 

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.

night light screen not working

Hi yuvalgoel,

In Windows 10, Night light depends on your PC's graphics driver to adjust the color temperature to reduce the blue light. If the video card driver isn't compatible with your system, there's a possibility that the feature will not work correctly.
If the issue is caused by incompatible device drivers, I suggest that you manually install the latest video driver to resolve this issue. Visit your PC manufacturer’s support website to download the latest graphics driver and follow the instructions provided
to update your device driver.

You may refer to this article for steps on updating drivers in Windows 10.

If you need further assistance, let me know.
