Remember the days when Microsoft was mocked for having half a dozen editions of everything? Those days might be back. There are a few versions of Windows 10 already, with more from the server and enterprise coming soon. And now there are two versions of Microsoft Office in the Windows Store, in addition to the standalone Office suite. The full desktop versions of Microsoft Office applications are now available as a Universal Windows Platform or UWP apps, and we all have Windows 10 S to thank for that.
