I believe that we use MySQL have overweight experience, if the reload MySQL is basically in the last step through but, unless the operating system, the reason is that the system's registry is not deleted clean. Here are some of the lessons I've summed up: the lesson of blood
1. Type regedit into the registry in run.
2. Heky_local_machinesoftwaremysql Directory Deletion
3. Hkey_local_machinesystemcontrolset001serviceseventlogapplicationmysql Directory Deletion
4. Hkey_local_machinesystemcontrolset002serviceseventlogapplicationmysql Directory Deletion
5. The Hkey_local_machinesystemcurrentcontrolsetserviceseventlogapplicationmysql directory deletes the controlset001,controlset002 in the registry, Not necessarily 001 and 002, may be ControlSet005, 006, and so on, delete the time, you can
6. Delete the MySQL folder under C:documents and Settingsall usersapplication data
7. Finally uninstall MySQL.
8. Delete the folder under the MySQL installation path.
9. It's best to reboot the computer.
ok! (Fire network tip: The above method in the MySQL version is MySQL 5.0 can be a successful reload, the other version needs to be verified)
(Of course Windows7 Uninstall after the MySQL does not seem to have more than a few registry entries, so under the Windows7 can be normal reload)
