TKS John it worked
I had bought a BB 8100 on eBay that had a password lock on it and did give to option to remove only change.

I was following the steps, and got to the part to copy the .bin file (my pearl was synced the entire time for a backup) when I disconected it and went to wipe it and the password lock was gone (i.e. the little red star at the side of the change password box). I did not need to do the regedit part, so those who are afraid of this you might not need to do it. and lauragal is right the file path of the registry you are using cannot affect the computer unless you do something really wrong. Remember system restore it was made for that reason.
