How to fix
Night light not turning off
on Windows

Hello. I have a Windows 11 laptop and the night light option is not turning off. I don't want to use it during the day as it is not comfortable. Is there a way to fix this?

The night light feature in Windows is designed to reduce strain on the eyes when viewing the screen for extended periods. It does this by emitting warmer colors, which are easier on the eyes and can even help with sleep. The night light feature can be especially helpful during the night when the surrounding environment is dark and your eyes may struggle to focus on bright colors. 

Research has shown that the warmer colors produced by the night light feature can help reduce eye strain and even induce sleep in some people. It's worth noting that the night light feature is not just available in Windows, but also on iPhone, Macbook, and Android devices.

However, some users have reported that the night light feature is not turning off in Windows 11, which can be a problem if you prefer to use it only at night. There are a number of different ways you can try to fix the issue if the night light feature is not turning off in Windows 11. One solution is to check the system settings to ensure that the feature is properly configured. You can also try reinstalling or updating your graphics driver,[ref en-1] as this may resolve any issues with the night light feature.

Another option is to modify the registry, which is a database of configuration settings used by the operating system. This can be a more advanced solution and should only be attempted if you are comfortable working with the registry. It is always a good idea to make a backup of the registry before making any changes, as this will allow you to restore the previous settings if something goes wrong.

There are other methods you can try as well, such as adjusting the schedule for the night light feature or manually turning it on and off. In this guide, you will find 6 steps that should help you fix night light not turning off. However, keep in mind that this can be also caused by an underlying system issue.
