So I am not able to login to the tablet and use it.
I am not able to reinstall the Windows 10 to create a new user.

Could you please help me to install a fresh Windows 10 an that Corebook.

Thank you,

Hi coyotefert,

the only way that worked for me to delete the Administrator password was the one under Linux.
But after that the Windows profile of the Administrator user was corrupt and I am not able to do start any application under Windows.
