I saw this query in a different thread:

A dev confirmed it. I just looked in my registry, and I don't see it myself. Still, you might have better luck.

I looked through all of my appdata folders and saw nothing regarding Cleverweek or Two Digits, so presumably it's still just in the registry somewhere... just don't know where it turned up.
