The existing My Office app has many of these features, but the new Office app puts the focus on the free online versions of Office if you’re not an Office 365 subscriber. It’s a free app that will be preinstalled with Windows 10, and you don’t need an Office 365 subscription to use it. It’s essentially a hub for launching recent documents, accessing the Office desktop apps, or simply finding the free web versions of Office. It’s replacing the “My Office” app that currently exists, and it’s designed to be a lot more useful to Office users. Microsoft is making a new Office app available to Windows 10 users today.
