So it would be interesting to tease out the differences between your 
machines and the ones I have access to.

What is your CPU? Maybe Windows 10 only sets these fields for recent 
enough CPUs?

You said you have all the latest updates. The most recent Windows 10 
version I have is 2009 with all the updates up to 2021-05-03. Do you 
have 21H1 already?

Can you think of other aspects that could make a difference?
