I noticed the registery key "NvCplAppNamesStored" is no longer used for Nvidia Profiles. You were able to delete profiles in there, but how is this done now? Since some of them can't be removed via the Control Panel (delete button blanked out).
registry has not been used for profiles since drivers were still called Forceware. this is just a location for detected applications.
I'm not sure, but you could try to use Nvidia Profile Inspector (the red X on top) and see if that works for those profiles.
