About this article, apparently microsoft just stopped to let users upgrade from win7 or 8 to win 10/11, causing the issue we're all talking about in here.
BUT: I did purchase a win 10 pro license, full price, and still suffered this annoying issue, after the win 11 upgrade and the BIOS flash. My personal opinion is they do not have a clue where the problem is, this problem is far to be addressed :(
