With the May 2014 release of the Office 365 Pro Plus Click To Run, Microsoft introduced the ability to install less than the entire Office suite.  Prior to this, enterprises installing Office 365 Pro Plus using *Click To Run* (NOT Windows Installer / MSI) could only install the entire suite - just like when 365 Click To Run is pull installed from the Microsoft Office 365 portal.  Awesome move Microsoft!  Many companies are planning to push only Lync 2013 Click To Run and follow up with the full Office Suite later or perhaps will need to add OneDrive at some point.  This raises an interesting question... How do you tell what 365 sub-products are already installed?
