You always could have disabled Cortana (no longer a thing btw) and you can disable Copilot if that’s what you thought about. Edge is another story, it does provide other functionality (WebView2) and is not just a Web browser so there is no official way to disable it. There will be something close to disabling it, but I doubt it will be truly removed from OS, just hidden from sight. Use another browser and forget it is there, I see it only if I explicitly search for it.
If you want to truly make your OS yours and fully remove most of the stuff you do not want, Windows is not and never will be for that, ″King of customization″ title belongs to Linux.
All we have here is people losing their minds over a new feature that can be disabled.
