Configure Windows Creators Update Night Light via Registry

Windows 10 Creators Update has many new features, one of which is Night Light. This feature helps reduce the amount of blue light emitted from your display to help reduce eye strain during night time use. However, the feature is not enabled by default and must be configured through the Windows Settings app. For IT admins who need to deploy Night Light across multiple computers, this article will show how to configure Night Light through the Windows Registry.

The Windows Registry is a hierarchical database that stores configuration settings and options for the Windows operating system. It contains information and settings for all hardware, software, users, and preferences. Each key in the registry contains values and subkeys that store information about individual settings. The registry can be accessed through the Registry Editor, which is a tool for managing the registry.

To configure Night Light via the registry, open the Registry Editor and navigate to the following key:


Once at this key, create a new DWORD (32-bit) named \EnableBWR\ and set its value to 1. This will enable the Night Light feature.

Next, create another DWORD named \NightLightLevel\ and set its value to the desired brightness level. This value can range from 0 to 100, with 0 being the least bright and 100 being the brightest.

Finally, create a DWORD named \NightLightTemperature\ and set its value to the desired color temperature. The available temperatures range from 2700K to 6500K, with 2700K being the warmest and 6500K being the coolest.

Once the registry keys have been configured, Night Light will be enabled and configured to the desired settings. It is important to note that these changes will not take effect until the computer has been restarted.

For IT admins who need to deploy Night Light across multiple computers, the registry keys can be exported from the source computer and then imported into the registry of the target computers. This can be done using the Export and Import commands in the Registry Editor.

By configuring Night Light through the registry, IT admins can easily deploy and manage the feature across multiple computers. This can save time and effort for admins who need to deploy Night Light across a large number of computers.
