Topic: Versions of sets (kits) for Windows

Somebody in course, by what principle for various components various Windows Kits (SDK, WDK, HLK, etc.) identical numbers of versions are set similar, but not? For example, on site MS it is offered last SDK 10.0.16299.91, however the file winsdksetup.exe in VS_VERSION_INFO contains 10.1.16299.91. MSI in directory Installers also have 10.1 in version number. The same leapfrog and in all remaining sets: in one places - 10.0, in others - 10.1. It has any reasonable sense, or these zeroes-edinichki at them undertake from ?
