Man, I'm a sucker for the Win 3.11 UI. I wish there was an option to use this style of UI on modern systems.

No idea how much of this began in Windows but Windows 3.1 was an OS that had it all and it was very strictly followed in a coherent interface.
Sure, I liked the Windows 9x/NT/2K UI too but 3.x was special to me for being early to be so complete in terms of usability.
I'm not big on visual file management. I do most of that through the command line.
Windows 95 was quite revolutionary because it brought in a very consistent look and feel to the UI.
