How to Fix Night Light Not Working in Windows 10

Windows has a built-in feature known as Night Light that enables users to use their computers for longer during the night without discomfort. Night light makes the display color warmer which makes it easy to stare at the computer screen when its dark. The night light is recommended especially for users with eye problems. You may encounter an issue where the Windows Night Light won’t work or when its greyed out in the settings. This step by step tutorial has a few methods that will help fix your Windows Night Light feature.
