Simple Classic Theme brings back the classic Windows theme to newer versions of Windows.
It does include a setup wizard that automatically installs everything you want.
Simple Classic Theme will install and configure either the SCT Taskbar or Open-Shell and StartIsBack to emulate the classic taskbar/start menu experience. It also enables/disables Classic Theme with a button press (or command). Simple Classic Theme runs the Classic Theme so that both Explorer and Immersive apps will run normally. You can also set it to automatically enable the Classic Theme on boot-up (if enabled before shutdown).
Optionally, during setup Simple Classic Theme will allow you to install all these utilities:
Uxtheme Multi-patcher will allow you to use any 3rd party msstyle theme on Windows (with Themes enabled) just by patching the uxtheme.dll (dynamic link library).
