To completely remove MySQL (preferences etc), you need to uninstall it and then remove the corresponding directories.

As you're using 64-Bit Win 7, the directories you should delete are (most likely):

  1. C:\Program Files\MySQL *\
  2. C:\ProgramData\MySQL *\ (ProgramData is a hidden folder)
  3. C:\Users\yourname\AppData\Roaming\MySQL *\ (AppData is also a hidden folder)

When you've done that, you'll be able to reinstall using a completely new password.

All that said, you don't need to do this. You can instead reset the root password.
