The issue is that a Windows 11 laptop is basically unusable out of the box unless you sign up/use a Microsoft account. This is unprecedented, as any computing device beforehand can at least perform its basic function without requirement to sign in to any sort of online accounts. Macs, iPhones, Android, all can be functional out of the box without having to sign into any accounts.It depends on when you installed your Win 11.
Local setup logins disappeared from Win 11 Home some months ago.
Local setup logins are disappearing from Win 11 Pro currently.
There will, I understand, be an exception for Win 11 Enterprise, but you will have to log in to your local Windows Server.
I believe, but I haven't bothered to do it, that once you have set up an initial login tied to a MS Account, you can set up a local log in.
As the nice man in the MS shop said -- "All your data is belong to us".
Well, not if I'm using Ubuntu...
And my surprise is, everyone thinks this is okay.
