Lightswitch is a lightweight system tray applet for Windows 10/11 that allows you to toggle nightlight on or off, as well as easily open nightlight settings. That's it. That's all it does.

Installation

Lightswitch is shipped as a single executable, just download and run.

Build instructions

The project should compile in a suitable Windows build environment. I include my .vscode files, so you can build with the exact same compiler flags if you use VSCode.

Credits

This project would not have been possible without kvnxiao's remarkable work reverse engineering the Compact Bond v1 format Microsoft uses to store the nightlight state in the registry. A tremendous thank you to them!
