ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Hi

I'm currently trying at MySQL and just logging in seems to be a challenge!?

>mysql -u root
If MySQL itself asks for the password, I can log in as desired.

>mysql -u root -p'xyz'
However, if I enter the password directly on the command line, strangely it doesn't work.
|mysql: [Warning] Using a password on the command line interface can be insecure.
|ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Can anyone explain to me??
Thank you!

PS: I'm using the latest version on Windows, but I have the same behavior on Linux.
