To explain how to remove System, User and File Data Source Names (DSNs) from the Windows Registry along with the Oracle ODBC Driver used to create the DSN.

Additionally, users may encounter an Oracle ODBC Driver who's version is listed as "Not-Marked" when viewing it in the ODBC Data Source Administrator. These steps will show you how to manually remove DSNs and unregister the Oracle ODBC Driver from the registry resolving any "Not-Marked" issues.
