Windows 10 has a hidden dark theme that you can enable via registry. Follow these steps to resolve:
Run – regedit – Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes
Right click on Themes and create a new key called “Personalize”. Inside of it, add a DWORD where “name=AppsUseLightTheme” and leave the value as “0”.
Navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize. Add the same DWORD name and value here.
Either logout and log back in or just do a reboot for it to take effect.
