Personally I still prefer what’s called Win-7 Pro x64.
Agreed. IMO that particular release was the Windows OS high-water mark, the "sweet spot", in terms of functionality, ease of use, and overall style. Everything before it was not as good, and everything after it has been worse.
It's a shame that it's now manifestly unsafe to use for internet browsing, because Microsoft stopped patching security flaws almost two years ago. But it's still entirely fine for local "air-gapped" use with applications.
