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

[alejc]

I can't create a privileged user "foo" password "foo", neither by MySQL console, Nor by PHPMyadmin (USAGE Grant No)

I am running Unicontroller.exe with administrator privileges, but this happens regardless of whether Unicontroller.exe is run with or without administrative privileges. In both cases the result is the same.
The root password is root and has ALL PRIVILEGES (Grant Yes)

SO:Windows 10/11 x64

I tested with versions 15_0_2_ZeroXV and 15_0_1_ZeroXV and both have this problem.

Trying to do it by CMD console:

C:\UniServerZ\core\mysql\bin>mysql -uroot -p
Enter password: ****

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

PD: I disabled UAC but the problem persists

PD: This doesn't happen to me with Xampp or Wamp

How do I fix this problem? Thanks
