This method may be useful on a development machine to remove all traces of trial licenses etc., but should not normally be used on an end-user machine just in case there are licenses installed by other vendors

Depending on the version of windows, and the permissions of the user, it is possible that not all licenses will be removed, espeically if they were installed by an administrator, but this method is invoked by a less privileged user.

Note that functions previously used during an execution remain available after this call, despite CurrentLicense

Target Platforms: .NET CLR 3.5 or higher
