Windows NT 3.51
NT uses a client/server architecture unique among these OSes. Hardware calls and other low-level manipulations are virtually impossible with this setup. Applications must instead invoke services via local procedure calls. While extremely secure, this configuration slows some performance, particularly in games, which like to write directly to hardware. Like OS/2, Win32 and Win16 applications run in separate memory spaces, and you can choose whether Win16 applications will run in the same or separate memory spaces.

theoretical--and no language better exemplifies this than C++.
