  • Delete the MySQL service
    • Open a Command Prompt in Administrator mode (search for Commadn Prompt, right-click over it, select Ran as administrator)
    • type sc delete MySQL
  • Uninstall all MySQL software
    • Go to Control Panel, Programs
    • Uninstall MySQL Administrator, MySQL Tools,, Connectors, and finally MySQL server
  • Delete the User files:
    • Navigate to C:\Users\[username]\AppData\Roaming (the "AppData" folder is hidden so you need to type it)
    • Delete the MySQL folder
  • Delete remaining files under C:\Program Files and C:\Program Files (x86)

Now you can install a fresh copy of MySQL, and import the saved database.
