I lost my administrator account in windows 10

  administrator, operating-system, windows

I have a computer with windows 10.

And I’m facing a massive hassle with my computer.

I was messing around and that I somehow lost my administrator account currently there’s only 1 standard account on my pc, currently I am facing such a big amount of issues.
For example I can not install anything…!!!

I did not found anything on internet that convincing and legit.

Tell me a way to format fully without admin rights like simply a replacement of empty computer with Windows 10 in it.

Or any other way to get back my admin account without using any third party software.
