So you had an account with adminstrative rights and you disabled it? Now you only have standard user accounts? Correct?

Do this Built-in Administrator - Enable from WinRE

Yes I had administrator accaunt and forget to my user change to administrator user...

Is that safe man
Can you tell me is it SaFe my windows don't crash after that insallah

fix worked?

It just patches a registry entry so built-in admin account will be active. It's very safe!

I see you also posted in Built-in Administrator - Enable from WinRE
Did you save enableadmin.exe on your desktop already?

Yes I now save it
But my is problem when I did this on that turtorial you share me in one UAC show up and say: Do you allow acces this program ... bla bla and he just let me to choose No he not let me Yes to chosse

In the 5 step when i chose config folder/file UAC show up and let me just to click on No
