How to enable ‘Dark Theme’ for Windows 10 apps
As in certain settings windows and calculator and so.
This is done on a Windows 10 Home 64-bit computer (works the same on a 32-bit one). And, this is done with caution since you will be using a tool that can mess up things if done the wrong way. Done correctly, it’s ALL safe.
This is being all done inside Registry Editor. Which you open from Run by either pressing WIN + R or right-click the Start-button and select Run. Type regedit and click OK.
If you’re on a regular computer that’s not played with too much. UAC will now ask you if you want to allow Regedit. It will cover the entire screen. This screenshot was made from a tablet since UAC doesn’t allow screenshots when it’s in “secure desktop”, and it’s cut a bit.
in Registry Editor you now navigate down to
Where you right-click in the right window-pane and select New > Dword (32-bit) Value
And giving it the name AppsUseLightTheme, it will by default get a zero value which is actually want we want now. If you want to get back to the Light theme you only change the value of AppsUseLightTheme to 1 (in Hexadecimal format). Or just remove it.
That’s actually it. Now Windows 10 apps (calculator) etc uses the Dark theme since we told regedit to not use the light theme.
Sadly Explorer and so on doesn’t use the Dark theme.
And, I’ve seen it mentioned that you need to create a new key called Personalize under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes as well, and then create the AppsUseLightTheme value there. But, for me that have no effect at all. So, I skipped that part.
