My understanding is that the majority of users aren't even able to upgrade currently. If your average user tries to upgrade from the Windows Update menu, they will just see if their computer is technically able to upgrade or not (based on CPU/TPM stuff I think). Even if it is, you won't be allowed or ping to upgrade until they deem your configuration viable. I am not by my home PC, but I think the messaging they give in the Windows Update page even says the upgrade should be available around spring of 2022.

So while Windows 11 is "out" right now, it seems to be for people on the windows insider program, and will be slowly rolled out to the public into next year.
