If you're using Enterprise on a personal machine, you've messed something up. There are other ways beyond Group Policy in that environment that are probably causing what you're seeing. SCCM, Intune, Policies over the network vs local... that significantly raises the chances of something else stepping on your local Group Policies.
I've not had that problem on either of my Win 10 Pro machines when using Group Policy to disable things, over the last four years.
It's been a year since I've uninstalled Windows, but I believe Windows 10 Pro does not have access to the stronger GPO policies that enterprise has. Enterprise was the ad-free version for a while there, but I think it's just as bad as Pro now.
It's too easy for them to turn back on without me realizing it, and I'm not going to tolerate having to be that vigilant against something, my own computer, which has absolutely no reason to be hostile to me.
And you can't afford to fuck this one up. Microsoft Recall isn't just a virus, it's worse than just about any other virus. "Did you forget to double check Microsoft's bullshit on the wrong day lol enjoy your keylogger"
Until they lobby to get laws changed, many companies have legal requirements regarding PII that mean serious fines if CoPilot or Recall ever turn on in their environment (and if they're caught of course).
Windows is not going to fuck this up and force this on, handing easy legal wins against them to the world. They will have the normal configuration options available that they always do for features with potential legal liability attached.
Did you miss the recent security blunder with Government security and Microsoft? They didn't want to tell governments of a secuirty hole in case it meant lowers sales.
And you can skip most of the bullshit by setting up Windows using English UK instead of English USA (and then you can adjust your regional settings and keyboard however you prefer)
You know damn well how ridiculous that sounds. And if this is the answer to removing Copilot, no thanks. Linux works perfectly fine for me and my gaming needs.
