How to Enable Dark Mode in Windows 10
Windows 10 is equipped with a night mode / dark mode feature which functions to reduce the intensity of light so that it is more comfortable on the eyes. Apart from that, dark mode can also save laptop battery.
The majority of work windows and applications will follow this arrangement. However some apps may have no effect.
For example, Google Chrome also has its own dark mode which is not completely affected by Windows 10 settings. Even some websites like Youtube also have independent dark mode options.
If you want to return to normal conditions, go to Settings > Personalization > Colors. Then choose custom and on Choose your default app modechoose light.
