This is much ado about nothing. You go get a fresh new MS outlook mailbox (burner phone type of mailbox) and account and install Windows 11 with it.
This outlook mailbox is your new MS account to install Win 11. For example this one is fresh>>>> JOHNXYZ909@outlook.com ...... I did not complete my “taking” of this outlook name.
I think it’s just aggravating to those who like to just turn on their computer and not have to log in their microsoft everytime- al5hough im not sure if going with a Microsoft account can do autologins or not? I never installed with a Microsoft account. Also, folks want to keep ms as much out of their computing as possible, but it’s getting tougher to do these days. It is all just so intrusive these days. But that is the nature of the beast I guess.
