Have you ever worked with two or even more computers at the same workplace? Maybe by using a desktop computer and a laptop at the same time. If you did, you had to cope with two keyboard and a mouse or touchpad on each computer. Not very handy, especially not so if space was limited on the workstation.
Microsoft's Mouse Without Borders is a tool for Windows to use one mouse on multiple computers in the same computer network. This way you could use one mouse both on a desktop PC and a laptop, as long as both computers are connected to the same network and that the Mouse Without Borders software is installed on all computers.
You need to install the software on all computers that you want to control with a single mouse. When you start the program for the first time you are asked to if you have installed the program on another computer in the network. If you click yes, you see a prompt where you have to enter a security code and the computer's name to establish the connection.
If you select the no option, a security code is generated and displayed next to the computer's name.
You then need to repeat the steps for all computer systems that you want to control with one mouse. Please note that Mouse Without Borders is limited to four PC systems that you can use a single mouse on.
Once setup, you can use the mouse on all PCs as if it was a single desktop. You can move the mouse between PCs and work on each computer individually without switching input devices.
One interesting feature is the ability to drag and drop files from one computer to the other this way. Just select the files on one computer and drag and drop them to another to copy or move them to the second PC.
Additional options include locking all PCs or logging in on all at once. Here is a video that demonstrates the capabilities in the second half.
Mouse Without Boarders is a Microsoft The Garage project, in which Microsoft employees come together after work to build and invent. The program can be downloaded from Microsoft's Technet website.
