No Bernard.

You left out Windows 2000, so it's really (at least) Windows 10.

The earliest confusion is unresolved, as a Windows RT (runtime) was an integral part of PageMaker, and possibly elsewhere, before the "public" was aware of any kind of Windows at all. There apparently was a Windows 1 and a 1.3 (that I heard a little about) prior to Windows 2.1 which was really the first version to reach significant (if sparse) public awareness.

Although the distinction is seldom observed, Windows 3.11WG was also an essentially separate version, significantly different than "plain vanilla 3.11," and Windows 98SE possibly should also be counted as "distinct."

They may have deviated from normal counting over uncertainty about whether to recognize the commonly expressed opinion that WinME was so bad it shouldn't count at all - much like some people's current opinion of Vista.

And you've been around here long enough to know that ya can't kill the thread creep!
