Windows 10: Windows 11 - register to my account

I had upgraded my existing Windows 10 Pro to Windows 11 pro. Signed in with my MS account, is activated, all good.However, if I look online to my registered devices, under this PC name I see that it is still marked as the old Windows 10. I even re-named the computer and that name refreshed, but not the OS.Is there anything that I can do to show the correct OS? Do I need to do anything?

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Strange Windows 10 User Account issue.

Unfortunately I had done those steps numerous reboots, it just, reappears for no good reason. The base account isn't even a Microsoft account, it's a local account.

I haven't quite tried the built in administrator account on W10, but so far in my experience on my own computer, the built in account seemed to have absolutely no more control than I did on my own.

It's just strange, I go in, it warns me twice about deleting the account, then it's gone. Reboot, and it's back?

EDIT: Just to specify, both command line and Netplwiz both say only HIS account exists on the computer, it doesn't list this rogue account. This is what I meant in my first post about the fact that even Windows doesn't seem to believe it exists, HALF the time. *Frown

Just simply log in with your Microsoft Account.

Just go back to using a local account:
