The negative reaction to this kind of thing baffles me. I see it as a neat new feature that'll make my life easier. But if for whatever reason you don't like it... don't use it. No biggie.
Yeah, it's not like Microsoft's style to force or nag their users into using whatever product. Nobody ever had any trouble turning off Onedrive, or uninstalling Edge.
Just this morning I was noodling through my start menu, as you do, and on a lark I right clicked and uninstalled Cortana. (This is on Windows 10.) Windows has never allowed me to do that before. You could disable it, you could hide it, but you could not uninstall it. The option just was not there. Some update somewhere along the line enabled an actual uninstall and I don't know which one.
Immediately I had a hunch they were planning to replace it with some new bullshit. That's the only reason Microsoft would ever let it go.
There are many things on Windows people don't like: Preinstalled bloatware, Edge, Microsoft spyware. As you simply cannot disable them under Windows, the only way not to use them is to upgrade to Linux, it seems.
If it follows the same pattern for all MS features, there will be a check box to turn it off, but it will be on by default. So if you don't like it, turn it off and save your outrage, like me, for the absence of a vertical taskbar in Windows 11.
No. I have definitely had the "suggest ways to finish setting up" setting revert itself after quarterly Windows feature updates. There was no prompt and it never asked me. It also reverts my fast startup setting, which on my particular motherboard causes Windows to take half an hour to boot. So I tend to notice that one when it changes the setting behind my back.
I find this immensely irritating. (The "finish setting up" option is the one that causes it to nag you every ~5 startups to create a Microsoft account, if you are using a local account like a sane person.)
You can disable these in Group Policy Editor, if you are running Windows 10 Pro or any of its myriad enterprise versions, and have admin permissions. If you do that insofar as I have observed they stay disabled. If you are running Win10 home, I believe the trick still works where you can steal a copy of the Group Policy snap-in (gpedit.msc) from a Pro copy of Windows via flash drive or whatever and just plonk it in your Windows folder, and it works.
Yeah when stuff like that happens I start going through my install to get vengance. Eventually I intend to keep this machine as a windows machine and build my next computer with linux.
