There are plenty of times where you need to test something safely in your computer without having to install it on your main computer. Provided you have Windows 11 Pro, Education or Enterprise, there is a solution for that. And all you have to do is enable Windows Sandbox in Windows 11 and then test away. 

Windows Sandbox is a virtual desktop that runs on top of Windows 11 or Windows 10 Pro, Education or Enterprise. Once you enable it, you can download apps, test URLs and applications in isolation mode without impacting the host desktop, and once you close the Sandbox everything goes away.
