Windows 10: Night light wierd bug

Night light issue, at the home screen before I log in its a normal colour, when I log in to (ACCOUNT A, ADMINISTRATOR), the screen fades to the night light colour, normal if I have it switched on, but according to settings I dont have it switched on and if I do switch it on it turns even more orange.

The settings aren't greyed out since I can turn it on or off, but while it seems to be on, it says its off, If I log out to the home screen its normal colour, if I go to a different account (ACCOUNT B), its normal colour, and If I turn on the night light on account B it works like normal. If I log back into Account A, its the same issue, fades back into that weird orange. Doesn't go away.


I use an NVIDIA GeForce GTX 1080 as my graphics card, I have reinstalled from Nvidia website, updated, done everything, same result.

It also seems to be that If I don't use the Nvidia driver, and I use the Microsoft classic display driver, it works fine. But I need the Nvidia driver for good graphics obviously.


I have a video game, when I launch it, it automatically disables the night light, or does something to put it to normal colour, but I have to be in the game window. The game is Portal 2.

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.
