I use ***StartIsBack***
to make Windows 8 look more like Windows 7. It's not free, but it's low price (though it's gone up in price since I bought it). They keep it up to date, so there's a version for 8.1 as well as a version for 8 (in case you bought the original Windows 8 and haven't updated). I originally wanted the Windows-looking Start button, which is/was available as a separate download. But then decided I liked the clover better anyway.
For a free one, I'd recommend ***Classic Shell***
. It doesn't look quite as pretty as StartIsBack, however it has a lot more options. It allows you to tweak your Windows Explorer to be like the one in Windows 7 or XP. It has the option to show the full path in the address bar instead of the "breadcrumbs" display without having to click on the address bar each and every time.
If anyone has managed to play Still Life in Windows 8 or 8.1, I'd like to know how they did it. The only person I know who managed to do it had a pre-release
version of Windows 8. Post Mortem seems to have the same problem. Windows 8 and 8.1 have fewer compatibility settings than earlier versions of Windows. The Windows NT and Windows 2000 compatibility modes that got some games working in Windows 7 are gone from Windows 8, and any game that needed them won't work.
