MySQL Forums

Better yet:

Go to Start -> Run
type cmd and press enter

This will bring you to the command prompt. Type "sc delete MySql" and hit enter. It will give you some sort of confirmation saying the service has been deleted.

This will delete MySql as a service. For some reason, XAMPP for Windows has problems running MySQL as a service, so do not check that box. Also, when you click the "Admin" link from the XAMPP control panel, it attempts to start MySQL as a service as well. Just don't do that. Any settings you need to change for MySQL should be modified by changing the config files directly with your favorite text editor, or you should be able to use PHPMyAdmin.

Hope this helps.
