I would like to uninstall add-on modules that I no longer wish to use.
You can uninstall certain add-on modules by going: Start menu > Control Panel > Programs and Features, and look for the modules you'd wish to uninstall:
Note: The modules you can uninstall do not include the core modules. Once you are on the Programs and Features window, you will see if it is possible to uninstall the modules in question. The Uninstall option will show at the top, otherwise the modules can not be removed.
