The recent anniversary update enabled a dark theme on Windows 10.  You can try this at home.  The trial versions I don't think downloaded the anniversary update.  The dark theme can also be applied with a registry hack.

Windows 10 comes with a hidden secret Dark theme mode which can be unlocked and tested in Modern (metro) apps:
1. In Registry Editor, go to following key:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize
2. In right-side pane, create a new DWORD AppsUseLightTheme and leave its value to 03. That's it. Now you can enjoy dark UI in all modern apps including Settings app.To restore default UI, delete the new DWORD AppsUseLightTheme.PS: In previous testing builds of Windows 10, the DWORD was actually SystemUsesLightThemewhich was replaced with AppsUseLightTheme in final version of Windows 10.UPDATE: Now this dark theme feature is officially available in Settings app:=1em[Tip] Enable Dark or Light Theme Modes in Windows 10
