That key isn't created by the portable app - did you have it installed locally, maybe?
As Magibon hasn't responded to Gord's question above and, in my testing, no key is created on Windows 7 x64 in the location specified, I'm going to close this bug. If Magibon replies or anyone else experiences this, we can always re-open it.
Sometimes, the impossible can become possible, if you're awesome!
