That does not answer the question? 10.0.22621.900 seems to be the latest and 10.0 just a prefix for all of them.

As an example from https://superuser.com/questions/296020/windows-kernel-name-v... lists

> 6.1.7600.16385, 6.1.7600.16539, 6.1.7600.16617, 6.1.7600.16695, 6.1.7600.16792, 6.1.7600.20655, 6.1.7600.20738, 6.1.7600.20826, 6.1.7600.20941, 6.1.7601.17514, 6.1.7601.17592, 6.1.7601.21701

Are these all just 6.1? Or is 7601 a different version than 7600? Could I choose to stay on 7600 and get backports or do I have to switch to 7601?

You could choose to stay on Windows 7, that is NT 6.1, and Microsoft will still backport updates from newer kernels such as NT 6.2 and NT 10.0 for the support life of NT 6.1.

That is nice, but that was not my question?

>Are these all just 6.1?

Yes. The numbers after the Major.Minor numbers are just revision and build numbers of little consequence for most people.

Are you here for thoughtful conversation or are you just being a Micro$oft Windoze troll? Because I can't tell; I would presume most people here know how to read version numbers.

I had to ask you three(!) times to finally get an answer to a simple question and then you go "major versions are obviously of little consequence; that is why they are called major". Clearly someone is trolling, but it isn't me.
