Windows 10 Had a dark theme which is much easier on your eyes.
To enable it run the following command:
REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize" /v AppsUseLightTheme /t REG_DWORD /d 0 /f
Log off and back on again and presto! The background colour for the Windows 10 menus will be dark.
If you decide you don’t like it, just run the command:
REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize" /v AppsUseLightTheme /t REG_DWORD /d 1 /f
Log off and back on again and its back to normal.
