Fix Night Light Options Are Grayed Out in Windows 10

Windows 10 allows you to enable Night Light mode (previously known as Blue Light) to reduce eye strain. When enabled, it makes the screen color gamma more comfortable for your eyes at night by reducing blue light. Colors become more warm and the backlight
will be dimmed, so eye fatigue will be less. Some users are faced with a strange issue where the Night Light options are grayed out in the Settings app. Here is a quick workaround to resolve this issue.

Night Light is a very useful feature for people who have to work on the computer during the night or in the dark. It keeps your eyes
relaxed and prevents them from getting strained. It is very frustrating if it does not work for some reason.

Normally, there are two ways to enable this feature. First is Action Center, where a special quick action button exists.

Click on the Night Light button to enable or disable it:



Alternatively, it can be configured in Settings under System - Display.



If these controls are not accessible in your Windows 10 instance, then try the following.

To fix the grayed out Night Light options in Windows 10, do the following.

1. Open the Registry Editor app.
2. Go to the following Registry key.
   
   See how to go to a Registry key with one click.
   
3. Here, delete the following subkeys
   
   
   
4. Restart Windows 10.

After restarting, Night Light should start working as expected.
