This section details on the original issue you should resolve

<issue_title>ASHWID description</issue_title>
<issue_description>There is a page describing ASHWID technical details, but it is in "outdated" state - https://docs.microsoft.com/en-us/previous-versions/windows/apps/jj553431(v=win.10)?redirectedfrom=MSDN
Has the ASHWID format changed?

And a related question - can ASHWID contain more than one CPU record?
