Windows 10 の最大 CPU/メモリの変更

Windows 10の最大構成(プロセッサとメモリ)が、Fall Creators Update(バージョン1709)からちょっと変わりました。

Windows Internals, Part 1』のおまけツール(slpolicy.exe)を使って色々調べていて(→)、Windows 10 Enterprise は 2ソケット/2TB が最大のはずなのに、4ソケット/6TBまで対応してると出て、おっかしいなぁと思っていたら、Windows 10 Pro for Workstations の登場に合わせて、Eneterprise エディション(たぶん Education にも)にも Windows 10 Pro for Workstations のスケールと機能が入ったということでした。

最新の状況を踏まえて、プロセッサとメモリの最大構成を一覧にすると...

※ Windows 10 S は想像です(Pro 相当なのでこれでいいはず)。
※ 論理コア数はすべて最大 256 らしいっす。
※ Pro for Workstations の x86って意味なくね?って思うかもしれませんが、ReFS とか SMB Direct とか Pro との機能差がありますんで。

ちなみに、おまけツール(slpolicy.exe)の出力結果は...
