How to completely delete MySQL database

Err, who can have no, Amen---------resolved as follows:

(episode: Sometimes "Confused" MySQL is restless, forget the password?? Delete files by mistake?? ... ... Of course, the following approach is "in case", but!!! You have to keep MySQL-related backups (important)! Don't mess up, be serious ... ）

"Problem description": After installing MySQL after setting the last step of the parameter verification, the third start service error in the Execute configurattion step, error Could not start the service MySQL, or fourth apply security Setting error.

"Problem": MySQL database of various types of problems ...

"Resolution steps":

1, stop MySQL services;

Start-->> Computer (right-click)-->> Manage-->> services and Applications-->> MySQL (right-click Stop);

2, the initial unloading MySQL;

Start-->> Control Panel-->> Uninstall program-->> select MySQL to uninstall

(!!! Note: It is absolutely not possible to manually delete the relevant files of MySQL, experience, the manual removal of the software, more or less will be residual "remnants");

3. Delete the registry information related to MySQL;

(1) Start-->> input regedit (register edit), open the registry;

(2) Hkey_local_machine/system/controlset001/services/eventlog/application/mysql;

(3) Hkey_local_machine/system/controlset002/services/eventlog/application/mysql (may not find, don't be discouraged, cut down OH);

(4) Hkey_local_machine/system/currentcontrolset/services/eventlog/application/mysql;

(5) So, after removing the above three items, MySQL basically unloaded completely. If you are not at ease, you can find MySQL in the C-disk, the relevant items are deleted;

(6)Win7 System Note that there is a file hidden deep (too cunning), it is possible that you can not find the third entry in the registry, C this situation (do not panic, the problem is to solve the drop). Remember when the installation of MySQL has something calledC:\ProgramData\folder, but did not find this folder, so it hides (will be invisible);Open the C drive .  -->>EnterProgramDatafolder, in the top left corner, clickTools-->> Folder Options-->> View-->>  selectedShow hidden files, folders, or drives-->>application determination, Just so!!!   (finally let it show up), open this file, sure enough, there is a MySQL folder, so decisive to remove him, in the installation, success! -----Game over!!

I believe MySQL has been installed successfully at this time! Congratulations, embarked on a Sunshine Avenue, a happy year!!
