Mouse Without Borders is a very useful tool from The Garage that allows you to reach across your PC’s as if they were part of one single desktop. For those who don’t know, The Garage is located at Building 4 at Microsoft’s Redmond HQ, where Microsoft’s developers and employees are encouraged to tinker about with their ideas and to incubate personal pet projects of its employees. Garage projects are side projects that Microsoft employees like Truong build for fun on their nights and weekends.

Mouse without Borders is a product that makes you the captain of your computer fleet by allowing you to control up to four computers from a single mouse and keyboard. This means that with Mouse without Borders you can copy text or drag and drop files across computers.  Mouse Without Borders was designed for people who use many computers in the same room. For example, a laptop or tablet that you take to meetings might sit right alongside the desktop PC in your office.
