Windows 10 Auto-Night-Mode automatically switches between the dark and light theme of Windows 10.

Windows 10 has Color settings that allow you to choose light or dark mode, but no settings to change this at a set time, for example. Enter Windows 10 Auto-Night-Mode.

When you enable the automatic theme switcher, it creates a task in the task scheduler of Windows that will start the app with the right arguments.

After installation, you can change a handful of settings. Choose Dark or Light mode and optionally change automatically followed by custom start times. Click OK, and you're all set.

Windows 10 Auto-Night-Mode fills an obvious (to most of us) gap in Windows 10 Light and Dark modes.
