Ever wish you could control multiple computers with the same mouse and keyboard? While there are a few ways to do this, the easiest by far is Mouse without Borders.
This free tool from Microsoft lets you control up to four Windows PCs with a single mouse and keyboard. Move your cursor to the edge of one screen and it jumps to the next computer. It’s as simple as that.
It’s built by Microsoft Garage, which is where a lot of the company’s more experimental and genuinely useful tools come from. Mouse without Borders has been around since 2018 and it’s quietly earned an avid following thanks to it being free and dead-simple to use compared to hardware KVMs.
Mouse without Borders setup is very easy and once done, you can arrange your monitors in the order you like.

Setup is quick. Install it on each machine, link them with a shared code, and arrange your monitors in the order you like. After that, you can drag files between computers, copy and paste across devices, and even sync things like lock screens. It can save you a ton of small, annoying steps throughout the day.
What’s interesting is that Microsoft recognized how useful this utility is and folded it into PowerToys, its growing collection of power-user features that are reliable and have stood the test of time.
If you run a dual-PC setup—work and personal or desktop and laptop—this is one of the easiest upgrades you can make.
