The second step is to delete the remaining MySQL files in the last installation directory, and don’t forget to delete the MySQL folder under ProgramData, as shown in the figure below. Note: The folders here are different from the residual files in the last installation directory. C:\ProgramData is generally hidden by default.

The third step is to press Win+R and enter regedit to run the registry editor. Follow the path in the figure below to find MySQL and then delete the MySQL registry information.

Step 4. After completing the first three steps, open the service and you will find that the MySQL57 service still exists, as shown in the figure below.
