As far as I know, Windows for Workgroups 3.11 was released before Windows 95, and went obsolete on the last day of 2001. However, it was still made available until November 2008. Why was that so?
I mean, online sources say that that was so because it was popular among embedded systems. However, for such systems you had Windows XP and Vista Embedded (Compact) versions too, so why was it still available for that long?
