I find it interesting how Windows 3.1 eclipsed 3.0.

While 3.1 in 1992 was a major upgrade with a saturated colour scheme, WAV & MIDI sound, and TrueType fonts—having clock.exe change from its 8-segment display—3.0 was the one that brought a major UI overhaul two years prior.

Despite everything Windows 3.1 brought, winver.exe reports it as “3.10.” As if the “.1” was a fraction—not a minor version—a 3% bonus on top of 3.0, the last part Microsoft was working on, not ready to distribute. Maybe it was a marketing decision like 4.0 being Windows 9.5?
