Well, the problem isn't windows 11. The problem is that the people upgrade instead of reinstalling it. 
Microsoft allows this because otherwise, 99% of people wont ever change their OS. 
But making an "upgrade" has at least a 50% chance that something breaks. It is quite obvious but sadly not obvious enough for the averge consumer.

If they offer this option, it should work properly, especially when it is aimed specifically at regular customers who aren't tech geeks. This is no excuse.
