Windows 10: Windows 10 Night light Greyed Out - Updated Graphics Drivers, No bluelight regedit entries

Hello, Night Light is greyed out I cannot turn on or off and it randomly turns on by itself I'm a designer I can't use my PC like this. Please help.

:)

 

Night light

Thanks Kapil

Intel UHD Graphics 630 driver up to date. Latest driver is October 2018.

Have tried regedit fix of deleting bluelight reg key-but no luck. Noticed that the 2 bluelight registry keys have no values set but assume that is default anyway.

As I have said in earlier post this is a Windows update problem. No doubt will have to wait months before it is sorted................

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.

I can't turn off night light (option is greyed out)

It wasn't the graphics driver I think (I was up to date at the time).

I solved it tough, but what I did isn't really a solution and I didn't identify the exact problem. What I did was go into Registry Editor and started deleting a bunch of registry entries related to "bluelight" until eventually Night Light
stopped being grayed out (both in Settings and in Action Center).
