G'evening Sky and welcome to the forums!

when keyclone is not running, it has zero impact on the system. no information is stored in the registry. no dlls are stored in the windows directory. and keyclone will not start up when you log in (unless you put it in the startup folder)

i hope that helps. if you have any other questions, please feel free to drop me a note.

have a great night and welcome to the addiction,

Rob
