What were the names of Windows 4, 5, and 6? | AnandTech Forums: Technology, Hardware, Software, and Deals
February 22, 2014 - Okay so there was Windows 1, 2, and 3. I'm not talking about the point releases, just the whole number releases. Is it like this? Window 95 = Windows 4 XP = Windows 5 Vista = Windows 6 I'm thinking that Windows 98 and 2000 were point releases of 95. I guess Windows NT could be considered "4" but I think that was more of a niche market, not a biggie like 95, which MS promoted the heck out of I remember.

r/explainlikeimfive on Reddit: ELI5: Windows Version numbers
2 weeks ago -
Okay so up to Windows 3 and its derivatives it makes sense. Then you gen Windows 9x and ME, which I understand to be all revisions of the same core at heart, so let's call that 4.x for numbering purposes. Then Windows 2000, which was certainly aimed primarily at business environments, but I remember having a 2000 PC as a kid, so unlike the other NT releases it seemed to have been a sort of hybrid home-business version, then XP, Vista, and back to numbers with 7. After that, there is the issue with 9, that makes sense to me as a compatiblity safeguard against software for 9x versions seeing 9 as part of the family, so no issues there, but that still leaves 4 release versions of windows in the space of just 3 numbers.

So, "Windows 2000, XP, Vista, 7, 8, 8.1, 10, 11" are just marketing names. The internal version number for these are 5.0 for 2000, 5.1 for 32-bit XP, 5.2 for 64-bit XP, 6.0 for Vista, 6.1 for 7, 6.2 for 8, 6.3 for 8.1 and 10.0 for everything from 10 onwards. Version numbers don't need to make sense and in Windows they absolutely don't.

The names of the Windows releases are simply a result of what Microsoft felt was appropriate at the time. The functional skip, as you wrote Windows 9. The whated year based on 95 and 98 for consumers, 2000 for companies and later on the server versions. They whated a non-number-based name for Me, XP and Vista. Then they returned to a number with Windows 7. Look at https://en.wikipedia.org/wiki/List_of_Microsoft_Windows_versions , and you will notice ther are version numbers too. When Windows NT was introduced, it had a separate number series from the consumer version until both merged in Windows XP , which was NT 5.1. From Windows 10 it has been replaced with a year bases system where 1607 was relase in 2016 in October that is month 7. It has changed to H1 for the first half of the year and H2 for the second half like 25H2
