Windows 10: Account Locked in a standard account

Hi there, I have accidentally changed my main windows account the one I use to a standard account and don't know how to change back to a administrator as I need to be able to download things and it isn't letting me saying I need to be an administrator. I have also lost access to my windows 11 administrator account as I don't know the password. am I stuck in a standard account or can I change back? I have looked all over the internet and cant really find a solution for this. any help would be appreciated. Thanks

:)

 

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:

 

Ubuntu account lock timer

There any way to change the timer that locks the account after inactivity or disable it?

 

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
