    How to Change Default App Mode to Light or Dark Theme in Windows 10


    In Windows 10, you can change your apps instantly from light mode to dark mode great for low-light conditions like working at night. When you make the switch, UWP (Universal Windows Platform) apps including Mail, Calendar and the Windows Store app go to a black background, which can even save your battery power with certain screen technologies.

    Starting with Windows 10 build 17666, dark theme support has been added to File Explorer, the File Explorer context menu, as well as the Common File Dialog (aka the Open and Save dialogs).

    Some UWP apps (ex: Microsoft Edge) allow you to change their theme independently of your set default app mode.

    This tutorial will show you how to change the default app mode to use a light or dark theme for your account in Windows 10.

    Currently this only seems to affect the Settings, Store, and Calculator apps in the example screenshots below.

    If you spot any others, then please feel free to post a reply with a screenshot.

    Found one! Voice recorder.

    Unless Microsoft codes File Explorer XAML instead of system32, I don't see it happening.And even then, this registry entry doesn't effect "all" Universal apps(XAML), for example News app.

    Tutorial updated to add OPTION ONE for Windows 10 Insider Preview Build 14316:

    Insider Announcing Windows 10 Insider Preview Build 14316 - Windows 10 Forums

    When you switch to dark mode, apps such as Settings, Store, Alarms & Clock, Calculator and other UWP apps that listen and respond to theme changes in the OS will change into dark mode. Some UWP apps that control their own theme settings (separate from Windows) won’t change by toggling this setting.

    Still no way to do this? Also, do you not have a dark theme for this forum? I couldn't find an option.

    To get a "dark mode" for file explorer you need to use "Color Filter" in ease of access, and that will change all your color settings on the whole system, icons, wallpaper, settings, app color mode(need to switch to light so it will become dark) inclusive. what it does is just invert all color settings. After switching to invert, you will need to re theme your system.

    Thanks. The color filter seems to apply to everything including shortcut icons. I found a theme called Blac & Grey in themes thread on this forum. I think it's made by you. It also changed the file explorer for me. Now I need some nice wallpapers because Windows Spotlight doesn't work like it used to for me anymore. I used to get mine from there. It doesn't ask me if I like them anymore after the update.

    I also applied the Dark forum theme. It's really nice. What is TF Responsive Don't Use?
