The solution to enter current root password when installing MYSQL

Eventually, the following solutions will emerge:

1. Clear the MYSQL installation directory and the default is C:\Program Files

2. Clear the MYSQL data storage directory, 1 in the C:\Documents and Settings\All Users. windows\Application Data directory

Note that the Application Data folder is hidden by default - by tool > Folder options - > See - > Show all

Files with folders to set hidden files visible.

Delete the MySQL folder

3. This step is very important. No matter how I uninstalled MYSQL before, I still had to enter the original password to clear the remaining files.

Delete registry data via regedit and delete the following files:

reference

HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Eventlog/Applications/MySQL

HKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Services/Eventlog/Applications/MySQL

HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Eventlog/Applications/MySQL

Finally everything OK!! .
