There are several options to bypass this. The easiest is to make a bootable USB drive using RUFUS with the installation media from Microsoft. You just pick the option to use a local account, and it still works just fine. If you go through the thread one of the posters provided directions and a link to do it another way using the command line.
I know a lot of people who get their panties in a wad about this, but there is nothing stopping you from using an alias with your new Microsoft account. You can use a $3 a month pay as you go cell account for your primary phone number and a Google number for your alias. These are handy for many other purposes as well.
Personally, I usually associate my installations with a Microsoft account that I use sometimes with as few as one computer. This can make it easier to keep using your retail license if you change your hardware or start with another clean install.
I was only asking because I’ve built out 50-60 Win 11 machines for various clients over the last year or two, and while the intaller tries to push you into using an M365 account, it isn’t necessary.
If this is going to change, it will negatively impact most of my clients.
This is also the first time I’ve heard of this and I signed up with for the public early access Win 11 beta test/dev team...
