A perfect solution for failed last-step MySQL reinstallation (experience summary) _ MySQL

The perfect solution for last-step failure of reinstalling MySQL (experience summary) I believe that everyone has had the experience of reinstalling MySQL. if I reinstall MySQL, it is basically not possible in the last step unless the operating system is reinstalled, the reason is that the registry in the system is not deleted. The following is a summary of my experience, which is a blood lesson:

1. type regedit in "run" to enter the registry.

2. delete the HEKY_LOCAL_MACHINE/SOFTWARE/MYSQL directory.

3. delete the HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Eventlog/Application/MySQL directory.

4. delete the HKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Services/Eventlog/Application/MySQL directory.

5. in the HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Eventlog/Application/MySQL Directory, delete ControlSet001, ControlSet002, not necessarily 001 and 002, which may be ControlSet005 or 006, you can delete all the files you want to delete.

6. delete the MySQL folder under C:/Documents Ents and Settings/All Users/Application Data /.

7. uninstall MySQL.

8. delete the folder in the MySQL installation path.

9. restart your computer.

OK! (Note: The above method can be successfully reinstalled when MySQL 5.0 is used. you need to verify it in other versions)

(Of course, after MySQL is uninstalled in Windows 7, it does not seem to have the above registry items, so it can be reinstalled normally in Windows 7)
