On: Microsoft ships Windows 1.0, November 20, 1985

Windows 3.0 was the first usable version, I think. You had multitasking, virtual memory (on the 386, anyway), VGA support, etc. That was less than 5 years later.

No file manager. 3.0 was a barely functional pile of crap.

3.1 then, a couple years later.
