Just delete the TH3 folder in "C:\Program Files\Cakewalk\VstPlugins" to remove the Cakewalk edition and then rescan your plugins. It does not affect the full version (or even the unlocked Cakewalk edition), because they are installed in "C:\Program Files\Overloud...", "C:\Program Files\Common Files\VST3" and in your chosen VST2 directory.
