You pointed the struct in this case, was this a mis-comment?

No, it's not a mistake. BOOLEAN is defined as enum.

May we define `BOOLEAN as enum : BYTE`? https://learn.microsoft.com/en-us/windows/win32/winprog/windows-data-types

I've specifically added that to access the whole value AsUINT64, maybe it's unnecesary right now, but added it as a plus. I took some inspiration from this code, that does the same:
xtchain/binaries/x86_64-w64-mingw32/include/winhvplatformdefs.h:29
(look for typedef union WHV_CAPABILITY_FEATURES)

I didn't notice the difference between i686 and amd64. In one case it is a structure containing 2 unions. Here we got 1 bit structure. Does it mean, that CPUID returns different data across archs?
