I'm still on 8.1. 
Aha! I will see your 8.1 and raise you ( lower you? ) To Win 7.1
Technically win 7 home premium SVC pack 1 (copyright 2009)
On a Toshiba satellite c655 ,
Celeron 900 2.2 ghz
4 GB ram
This a specially
castrated gutted version, heavily modded by myself
With many "features" removed, and certain specialty software added,
Which includes a variety of vpns to choose from, a strong "sandbox"
in which to run suspect items, and several frozen versions of modified browsers.
I actually bought several more copies of win7 on DVD with koshered product keys, just in case,
And over the years I have acquired 3 more old laptops with win 7 and an HP "all in one" desktop
Monster runningwin 7
I did kowtow to modernia and got an HP deskside running win 10 so I can run various commercial
crapNecessary software... But I promptly castrated that one too.
Especially the part about using MY machine as a repository to contact and update OTHER machines.
Oh my no.
I am already having to hack my air-conditioner because the evil ones think they can limit my lowest temperature setting. The day I have to hack a fridge or washer is the day I start collecting and rebuilding them too.... Damn this autocorrect!
I may have to hack my Subaru auto firmware. .. grrrrrr
We are now living in one of the dysfunctional futures where the "grey market" trades in illicit software mods that theoverlords do not want the citizens to have...
