Completely uninstall Mysql method to share _mysql

Reloading the system is always a good idea, but who likes to do it: (

It was later unintentionally discovered that unloading was not completely caused by unloading, and the following is a complete uninstall method for uninstalling MySQL 5.1:

1, the Control Panel in the Add Delete program to delete

2, delete the MySQL folder under the My.ini file, if the backup is good, you can directly delete all folders

3, start-> run-> regedit see the registration table these few places delete no

Hkey_local_machine\system\controlset001\services\eventlog\application\mysql Directory Deletion

Hkey_local_machine\system\controlset002\services\eventlog\application\mysql Directory Deletion

Hkey_local_machine\system\currentcontrolset\services\eventlog\application\mysql Directory deletion (I did not find the uninstall, slightly later still achieve the purpose of full uninstall.) ）

4, this article is very important

C:\Documents and Settings\All Users\Application Data\mysql

There are also MySQL files that must be deleted

Note: Application Data This folder is hidden, you need to open a folder select Menu bar tools → folder Options → view → hidden files and folders an option to display all files and folders ok

Above 4 steps complete, restart ok! Install it again.
