Mouse without Borders – Control up to 4 computers from a single mouse and keyboard

Mouse without Borders (AKA: Mouse w/o Borders) is a keyboard & mouse auxiliary tool released by Microsoft, developed by Truong Do from Microsoft Garage in 2011. This small tool allows user to use a set of keyboard and mouse to control multiple computers (up to 4), including copy/paste (i.e. share the clipboard), drag & drop, and other common file operations on different computers just like using the same computer, thus greatly improving the work efficiency.
