An improvement to the most useful answer here:

1] No need to restart the mysql server
2] Security concern for a MySQL server connected to a network

There is no need to restart the MySQL server.

use FLUSH PRIVILEGES; after the update mysql.user statement for password change.

The FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.

The --skip-grant-options enables anyone to connect without a password and with all privileges. Because this is insecure, you might want to

use --skip-grant-tables in conjunction with --skip-networking to prevent remote clients from connecting.

Do it without down time  Run following command in the Terminal to connect to the DBMS  you need root access      sudo mysql -u root -p    run update password of the target user  for my example username is mousavi and it s password must be 123456      UPDATE mysql user SET authentication string PASSWORD  123456   WHERE user  mousavi       at this point you need to do a flush to apply changes     FLUSH PRIVILEGES    Done  You did it without any stop or restart mysql service

While you can t directly recover a MySQL password without bruteforcing  there might be another way - if you ve used MySQL Workbench to connect to the database  and have saved the credentials to the  vault   you re golden   On Windows  the credentials are stored in  APPDATA  MySQL Workbench workbench user data dat - encrypted with CryptProtectData  without any additional entropy   Decrypting is easy peasy   std  vector lt unsigned char gt  decrypt BYTE  input  size t length        DATA BLOB inblob   length  input        DATA BLOB outblob       if   CryptUnprotectData  amp inblob  NULL  NULL  NULL  NULL  CRYPTPROTECT UI FORBIDDEN   amp outblob                 throw std  runtime error  Couldn t decrypt               std  vector lt unsigned char gt  output length       memcpy  amp output 0   outblob pbData  outblob cbData        return output      Or you can check out this DonationCoder thread for source   executable of a quick-and-dirty implementation

Unfortunately your user password is irretrievable  It has been hashed with a one way hash which if you don t know is irreversible  I recommend go with Xenph Yan above and just create an new one   You can also use the following procedure from the manual for resetting the password for any MySQL root accounts on Windows      Log on to your system as Administrator    Stop the MySQL server if it is running  For a server that is running as a Windows service  go to the Services manager                 Start Menu -  Control Panel -  Administrative Tools -  Services   Then find the MySQL service in the list  and stop it  If your server is not running as a service  you may need to use the Task Manager to force it to stop    Create a text file and place the following statements in it  Replace the password with the password that you want to use   UPDATE mysql user SET Password PASSWORD  MyNewPass   WHERE User  root   FLUSH PRIVILEGES    The UPDATE and FLUSH statements each must be written on a single line  The UPDATE statement resets the password for all existing root accounts  and the FLUSH statement tells the server to reload the grant tables into memory  Save the file  For this example  the file will be named C  mysql-init txt  Open a console window to get to the command prompt            Start Menu -  Run -  cmd  Start the MySQL server with the special --init-file option   C   gt  C  mysql bin mysqld-nt --init-file   C  mysql-init txt   If you installed MySQL to a location other than C  mysql  adjust the command accordingly   The server executes the contents of the file named by the --init-file option at startup  changing each root account password   You can also add the --console option to the command if you want server output to appear in the console window rather than in a log file   If you installed MySQL using the MySQL Installation Wizard  you may need to specify a --defaults-file option   C   gt   C  Program Files MySQL MySQL Server 5 0 bin mysqld-nt exe  --defaults-file  C  Program Files MySQL MySQL Server 5 0 my ini  --init-file C  mysql-init txt   The appropriate --defaults-file setting can be found using the Services Manager      Start Menu -  Control Panel -  Administrative Tools -  Services   Find the MySQL service in the list  right-click on it  and choose the Properties option  The Path to executable field contains the --defaults-file setting  After the server has started successfully  delete C  mysql-init txt  Stop the MySQL server  then restart it in normal mode again  If you run the server as a service  start it from the Windows Services window  If you start the server manually  use whatever command you normally use    You should now be able to connect to MySQL as root using the new password
