Sometimes we need to uninstall MySQL and reinstall it for a variety of reasons, but because uninstallation does not completely cause a variety of problems during installation. So uninstall completely when uninstalling. A step that is completely removed
1. Stop the MySQL service. Right-click on "Computer-select" Management, select "Services and Applications" in the pop-up dialog-"services", in the local service that opens, select the service named "MySQL", right-click, select "Stop"
2. Uninstall MySQL. Remove MySQL Server from the control Panel
3. Delete the remaining installation files. Delete the folder MySQL under the installation path (default to "C:\Program Files\mysql").
4. Delete the remaining service profile. Deleteall files under the path "C:\ProgramData\MySQL\MySQL Server 5.5\data" or delete the MySQL folder directly (ProgramData is a hidden folder that needs to be in the "Tools"- "Folder Options"-"view" tick to view hidden files. You can also search directly through the search bar)
And then there's no more, OK, finished
Completely remove MySQL
