Teaching myself to write plug-ins. Have generated some junk xxx.ny files in that process. Deleted those file from audacity/plug-ins folder but they keep showing up in the Add-Remove Plug-ins list. Tried reinstalling Audacity to get rid of them but they are still there. Where is that list maintained and how do I purge my junk from it? Jim
To purge the list of plug-in, delete the files pluginregistry.cfg and pluginsettings.cfg
You will usually find these files in the hidden folder "C:\Users<user name>\AppData\Roaming\audacity"
(where “” is your log-in name).
delete the files pluginregistry.cfg and pluginsettings.cfg
Really? I have to do a system level change to remove a plugin?
How about an Add/Remove Plugin button [Refresh].

Those are not “system level” files (despite the “registry” tag)- they are Audacity files.

No, but that’s not what jim asked:
The list of plug-ins is in the file “pluginregistry.cfg”
Settings for plug-ins is in the file “pluginsettings.cfg”
To purge all junk from those lists, just delete both files while Audacity is closed, then start Audacity. On start up, Audacity will recreate these files and they will be “factory fresh”.
What he says.
The current plug-in registration mechanism was written by Leland a few years ago. It was a big improvement over the previous version which had no mechanism for managing plug-ins. There have been recent discussions on the Audacity team mailing list about reworking the plug-in manager, possibly in time for Audacity 2.3.4. As you (Koz) are a member of the core Audacity team, you should be aware of that.
you should be aware of that.
I ought, yes.

Thanks for the directions. Sneaky hiding that stuff the way it was. Got it sorted out and I hope I didn’t cause too much internal friction. Jim
Super 
Not a problem Jim.
