Windows 10 activate by user without administrator rights?

I have the following problem:

I had two user accounts on my Windows 10 laptop from Microsoft. I rarely use one, so this morning I got the idea to hide it so that it can't be seen when logging in, then I went to the command prompt and wanted to deactivate the other account without administrator rights.

However, it then deactivated my account with administrator rights, so that the one with administrator rights is no longer displayed to me.

Then I tried to unlock the right one again via the other, which doesn't work because I don't have the necessary rights and my password is no longer correct for the account with administrator rights, so that I can no longer grant the current one.

So far, I have not found any explanation on the Internet. I would be really happy if someone can help me because I have saved all the data on the now no longer available account and built something up there, so that it is really important to me to get the other account back completely. I'm desperate.

Jabbadabbadu…

You just have to undo the registry changes offline, because you can no longer get there online. Hopefully this is not an important system - or: is there a current system backup? If not, now would be the ideal time to make up for it.

If your hard drive is not encrypted, you can use a rescue system to overwrite your passwords.

I've tried it doesn't work anyway, thank you, maybe you can think of something else

I've tried all of them, but none of them worked because I need the password for my admin account every time, but it doesn't accept it. I have not yet tried the "Bypass Windows 10 password with command prompt" option because I do not know whether it really works, because I will probably need the password again because it denies access. I've already tried it in the logged-in area but also before that, but as I said, access was denied to me. I also feel unsafe when booting. Do you have any other ideas? And how do I actually get into the BIOS when booting a relatively new Microsoft laptop with Windows 10?

If you start windows in safe mode, you will automatically log into your system as admin. Have fun

Into the BIOS with the Del / Entf key or via F1. Do you have to press when booting.
