Like said in the intallation page in the manual at step 10, you have to enter a strong password with at least one capital letter and one number, so Passw0rd or [email protected] should do the job. When you are logged in to windows you can disable this enforment via this tutorial.
The only mistake you can make during the installation is selecting a Server Core Installation in stead of a Full Installation, but I guess this doesn’t affect the creation of a new password at the first start.
Good luck! Hope you can log in now! 😉
