Mouse without Borders

Control multiple PCs with one keyboard and mouse

Mouse without Borders is a practical Windows utility for anyone who regularly works across more than one PC. Instead of keeping separate keyboards and mice on the desk, it lets you control up to four computers from a single set of peripherals, making a multi-PC workspace feel much more manageable.

The idea is simple: choose one main computer, then link the other PCs using its security code and computer name. Once connected, your mouse and keyboard can move between machines, helping reduce desk clutter and the constant switching that comes with separate setups. It is especially useful for people who use a laptop beside a desktop, manage several work machines, or like to split tasks across different PCs.

Mouse without Borders also includes a few thoughtful options that make it more flexible than a basic input-sharing tool. You can share clipboards between connected computers, configure keyboard shortcuts, and adjust whether the mouse is allowed to cross into other displays. These settings give users control over how connected the machines feel, which is helpful if you want convenience without accidental cursor movement.

In everyday use, its main appeal is that it stays focused on one job and keeps that job lightweight. It is not trying to be a full remote desktop solution or a complex system management tool. Instead, it is best viewed as a desk productivity utility for nearby Windows PCs.

The main drawback is compatibility. The version described does not yet work with Windows 11, which limits its usefulness for users who have already moved to Microsoft’s newer operating system. For Windows users with supported PCs, though, Mouse without Borders is a straightforward, customizable way to simplify a multi-computer setup without adding more hardware.
