Method 1:

1. input in DOS window

net stop mysql5 

Or

net stop mysql 

2. open a DOS window and switch to the bin directory of mysql.
Generally, a batch of 1.bats is created in the binlog. the content is "cmd.exe", and you can switch to the current directory, and enter

mysqld-nt --skip-grant-tables; 

3. open another DOS window.

mysql -u root 

4. input:

use mysql update user set password=password("new_pass") where user="root"; flush privileges; exit 

5. use the Task Manager to locate the mysqld-nt process and end the process.
Or the following steps
1. stop MYSQL. open the DOS window in CMD and enter net stop mysql.
2. in the CMD command line window, enter the MYSQL installation directory, such as E:/Program Files/MySQL Server 5.0/bin.
Demo command:
Enter e: enter,
Enter cd "E:/Program Files/MySQL Server 5.0/bin"
Note that double quotation marks must also be entered to enter the Mysql installation directory.
3. enter the mysql security mode, that is, when mysql is up, it can enter the database without entering the password.
Command:

mysqld-nt --skip-grant-tables 

4. open a new CMD command line window and enter

Mysql-uroot-p: use a blank password to log on to MySQL (press enter without a password)

5. enter the following command to modify the password of the root user (note: There is a "point" in the middle of mysql. user ")

Mysql. user: database name. table name
Mysql> update mysql. user set password = PASSWORD ('New password') where User = 'root ';
6. refresh the permission table
Mysql> flush privileges;
7. exit
Mysql> quit

So MYSQL Super Administrator account ROOT has been reset, then in the task manager to end the mysql-nt.exe this process, restart MYSQL!

(You can also restart the server)
After MYSQL is restarted, you can log on to MYSQL with the newly set ROOT password!

Method 2:

First, create a new pwdhf.txt under the MySQL installation directory, and enter the text:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('*****'); 

The red part shows the new password to be set.
Use windows service management tools or task manager to stop the MySQL service (Task Manager K drops the mysqld-nt process)
Doscommand prompt to the bin directory under the MySQL installation directory.

D:/Program Files/MySQL Server 5.1/bin
Then run:

mysqld-nt --init-file=../pwdhf.txt 

After the execution is complete, stop the MySQL database service (Job Manager K drops the mysqld-nt process), and then start MYSQL again in normal mode.

7. refresh permission:

FLUSH PRIVILEGES;

8. exit and log on again:
