Mouse Without Borders Not Working? 7 Ways to Solve It

As a writer, it’s my penchant to be more productive. I often take inspiration from other bloggers, YouTubers, and gamers using a multiple screen setup. So I set up a new desktop to accompany my old laptop. Since I was on a shoe-string budget, I decided to install Mouse Without Borders. To my surprise, it didn’t work.

Mouse Without Borders Not Working

Mouse Without Borders is a free app available at Microsoft Garage that often offers experimental apps and tools. This app allows you to use a single mouse and keyboard across multiple screens and different systems. However, Mouse Without Borders was not working as advertised.

Here are some possible solutions including the one that eventually worked for me. Mouse Without Borders works from Windows 7 to 10. It is seamless even if you have different Windows OS versions installed on separate computers.

1. Check Your Version

Are you using the same version of Mouse Without Borders on all computers? To check this, right-click on the icon of Mouse Without Borders in the system tray and select About.

2. Same Wi-Fi Network

All your computers must be connected to the same Wi-Fi network if you want Mouse Without Borders to work. To check, click on the Wi-Fi icon in the Taskbar and check the name.

If it is same, move on to the next tip, if not then make sure to connect to the same network as the other computer.

3. Compatibility Mode

It is not necessary to have the same version of Windows installed on all the computers. You can have Windows 10 on one and Windows 7 on another. In my case, Mouse Without Borders was not working even though I had Windows 10 installed on both. Some users discovered that changing the compatibility mode helped. To do this, right-click on the Mouse Without Borders shortcut on the desktop and select Properties.

Under the Compatibility tab, use the dropdown menu to select a different version of Windows than what you are running on both the computers to see if this works. Click on Apply and then OK to save changes.

4. Run as Administrator

Mouse Without Borders requires admin rights to move between computers and gain access to various settings. Maybe it lacks the necessary permissions? Go back to Properties as you did in the previous section and open Compatibility tab.

Repeat the same steps on all the computers that you want to use Mouse Without Borders on and try again. Close the app and relaunch it to check if it works across computers.

6. Enter IP Manually

Mouse Without Borders uses your Wi-Fi network’s IP address to connect with other computers running on the same network. Sometimes, the app is unable to detect the correct IP settings leading to this error.

Launch the Run prompt by pressing Windows key+R on your keyboard and type cmd to open the command prompt.

Don’t use the browser to find your IP. In the command prompt, type the below command and press enter Enter.

If Mouse Without Borders stops working again in the future, click on the Apply button again to initiate a new connection. That is a known issue with the app.

7. Synergy

If everything fails and you find yourselves pulling your hair in frustration, maybe you should consider a third-party tool like Synergy. It will cost you $29 for the Basic version. Synergy does what Mouse Without Borders does but also for macOS and Linux platforms. That gives you more free hand, especially if you are a programmer or other professional working with different operating systems daily.
