So why is 16bit execution supported on Windows 10 32bit but not on Windows 10 64bit or even Windows XP 64bit?

It seems to be this:

"The primary reason is that handles have 32 significant bits on 64-bit Windows. Therefore, handles cannot be truncated and passed to 16-bit applications without loss of data."
