How to Use the Mouse Without Borders and Peek Features in PowerToys

PowerToys is constantly adding new features, making it a handy utility for users looking to get more out of Windows. It started with a bunch of utilities but now has the most comprehensive lineup of tools including Mouse utilities, Image Resizer, and many more.

The new preview update introduces “Mouse Without Borders” and “Peek” utilities. We will elaborate on what these utilities do, and how you can enable and use them on your Windows PC. Let’s begin.

If you use multiple computers on your desk, you might have faced the issue of using your mouse on all the computers. While some Bluetooth mice can cycle between devices, you can not use one mouse to control all the computers as if they were sharing the screen.

The Mouse Without Borders feature makes it possible to share the mouse among multiple devices. Both computers will need the latest version of PowerToys installed on them. Earlier, Mouse Without Borders was a standalone app and competed with the likes of Share Mouse and other mouse and keyboard sharing apps . But now it is a part of PowerToys, so you don’t need to install it separately.
