Control Two Computers with a Single Keyboard and Mouse

Mouse Without Borders. If you’re only linking PC’s, Mouse without Borders’ really easy setup + bonus features might be what you want. It’s a wonderfully useful tool. In a nutshell, it allows you to reach across your PC's as if they were part of one single desktop.

I have two PCs on my desk at work connected to 3 LCD screens and using Mouse Without Borders I can move my mouse between the 3 screens, even though one of them is attached to a different PC from the other two. What’s more, I can move files between the 2 computers simply by dragging them from one desktop to another.
In fact you can control up to four computers from a single mouse and keyboard with no extra hardware needed – it’s all software magic, developed by Truong Do who by day is a developed for Microsoft Dynamics.
