After removing a certification extension, why does the CAPC user interface still say "Factory Extended" and can that be changed?
The CAPC UI still says "Factory Extended" because there is an extension in place, there is just nothing in it. The cert UI reports based on /rest/certhistory which records changes based on the typecatalog web service. There is no way to "remove" and extension. So once it is extended, it stays that way
