In order to keep that office-bound PC accessible on the road, Microsoft released Remote Desktop apps for both iOS and Android alongside the arrival of Windows 8.1. Now, users can navigate a Windows machine via a smartphone or tablet with the help of the Remote Desktop Protocol (RDP). The software doesn't detect PCs automatically, so you'll need to have that IP address handy and remember to toggle on the requisite options from the base station's Control Panel. Once inside the app, you can expect multitouch navigation, content streaming and a management tool for an entire collection of remotely connected devices. Both the iOS (iOS 6 and 7) and Android (2.2 or later) versions of Microsoft Remote Desktop are free and they await in source links that follow.
