Access denied for user ‘root’@’localhost’ while attempting to grant privileges.

ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES)
Entah kenapa tiap kali bikin user dan grant privileges selalu gagal, padahal biasanya gak pernah error.
kalo dirimu develop pake xampp. cukup buka C:MySQL Server 5.5bin>mysql_upgrade.exe
