deleting hidden wifi passwords

For security reasons i always disable the option autoreconnect when i connect to my wifi router.

Normally this means that no profile will be created,and I thought the pass was not saved.
Now i tried a program named "wifi password revealer" and, ssid and pasword is somewhere logged.
I have search the register with Regedit, but i could not find it.
Do someone knows where it is hidden and how i can delete it?

I don't know why you would think hiding the auto logon is a security issue. Does someone else have access to your computer or what?

You don't have to worry.
