Sometimes the local settings folder is hidden. If you don't see it in the folder with your username, type it manually in the address bar at the top of the file explorer window. Then go to temp. There should be a folder in there with your pin. It's there, you're just missing it. You can search for it even when the switch device wizard is not running. If you've run it once, the folder will still be there, but it will be empty until you start the switch device wizard.
JC, I'm told that Windows 7 doesn't have the Documents and Settings folder. It's C:\Users\username\ and so on
