Translation to English:
I bought Zorin at the end of last year. after using the trial version for a moment, I installed Zorin. I didn't need to sign up the program was running I had the feeling it was running a staked out version. I didn't do anything anymore because I had entered a password, and after a few days I forgot the password, nothing works anymore. that was my first Linux entry.
If you have forgotten your ZorinOS user password, then according to this thread the best thing you can do is reinstall ZorinOS again and use a new password. Forgot password
