Microsoft Remote Office offers the option of basic controls. After that, however, you should be able to launch any of the three Office apps and be off and running. The setup is a bit complex: after downloading the app, you’ll also need to set up a desktop add-in for Office Remote, a bit of code that facilitiates the control from the phone to the PC. Office Remote works with PowerPoint, Word, and Excel, with app-specific functions for all three.
(It does not run on Windows RT.) If you can manage that, however, the free app appears to offer everything you’ll need-including a virtual laser pointer, too. Microsoft’s new, free Office Remote app requires a Windows Phone, a version of Office 2013 for either the Surface Pro or a PC, and a Bluetooth connection between the two. Now, Microsoft has gravely wounded it with a single app. The lack of a simple, convenient way to steer PowerPoint presentations arguably birthed an entire industry of PowerPoint remotes.
