How To Automatically Toggle Dark & Light Modes On Windows 10

If you didn’t already know, your Windows 10 PC has a dark mode that helps reduce eye strain and makes your PC look darker. This option is in the Settings app, and you can turn it on or off at any time.

The dark mode is mainly used at night and the light mode is used for the day. If you also use it on your computer, you may have to manually switch the mode every day.

In fact, you can simplify this process a bit by creating a task that automatically turns dark mode on or off in Windows 10. Setting it up is pretty simple and you only need to do it once. Then it starts automatically every day and switches modes according to your requirements.

Use Task Scheduler to automatically enable dark mode in Windows 10
