Mouse Without Borders is a tiny but super powerful application that helps users to control up to four computers from a single mouse and keyboard at a given time.

Mouse without Borders is for Windows and allows you to effortlessly move from one machine to another while performing tasks like drag and drop or copy and paste text, screen capture and file across multiple machines.

Mouse Without Borders is a Microsoft Garage project by Truong Do. Garage projects are side projects that Microsoft employees like Truong build for fun on their nights and weekends.
