There are lots of users complaining that Night Light (Blue Light) mode settings are grayed out or not working properly after installing the latest Windows 10 Creators Update. Here in this article, you will read about the possible ways to fix this problem.
Night Light previously known as Blue Light mode is a useful feature of Windows 10 Creators Update that reduces eye strain while working on the laptop or desktop for a long time, especially in the night. When this feature is enabled, it lowers the blue light on the screen at night time which in return reduce eye strain and enhance sleep quality. The color of the screen become warmer and the backlight will faint which in return lower the eye fatigue.
Unfortunately, there are lots of users reporting that few bugs affecting the feature from working properly. Some users saying that Night light feature does not turn off automatically the schedule. While other reporting that the Night Light options are grayed out in the Windows 10 Settings app.
It is really a useful feature for those users who work on their Windows 10 PC or laptop late at night and it is really frustrating if the feature is not working properly. by keeping this thing in mind I decided to share a workaround that helps in fixing the issue.

Yes, it is available for Windows 10 and you can run this tool unless Microsoft acknowledges this issue and fix the problem. You can check my previous article on the F.lux app for Windows 10 to know more about the tool.
