When running software from unknown sources, you may encounter malware of any sort, without even knowing it. To avoid contaminating your system, you can use a sandbox system before installing. These services allow you to create a safe environment where you can install anything without harming your primary system.
Windows Sandbox is a built-in Windows feature that gives you a temporary, isolated copy of Windows for testing and running software from untrusted sources. It gives you a copy with a clean desktop, just like your regular one, but with one key difference. Everything inside is disposable: when you close the window, all files, apps, and changes are wiped.
Because it uses hypervisor‑based virtualization and its own kernel, anything you install or run inside the sandbox is kept separate from your main system. It's a great option for trying out tools, opening suspicious attachments, or visiting risky websites without having to set up a separate virtual machine.
Why Should I Download Windows Sandbox?
Windows Sandbox is helpful any time you want to try some kind of new software or download an attachment without risking your main PC. You can open a fresh copy of Windows in its own window, install a program, change settings, or open a file you are unsure about, and then throw it all away by closing the sandbox. Each time you start it up, you get a clean slate again, so nothing you did in a previous session carries over or takes up space on your computer.
It is also a good tool for everyday security tasks. You can browse unfamiliar sites, run installers you are unsure about, open email attachments, or test browser extensions without putting your main space at risk. If you work in development or IT, it can be used as a quick way to test compatibility or demo software instead of setting up and managing lots of separate virtual machines just to test different apps or files.
Is Windows Sandbox Free?
Windows Sandbox is included with certain Windows 10 and Windows 11 editions, such as Pro, Enterprise, and Education, and is licensed through the existing Windows licenses for those editions. If your device already runs one of these supported editions, enabling Windows Sandbox is a matter of turning on the feature rather than purchasing software.
There are no additional subscription tiers or per‑user fees specifically tied to Windows Sandbox. The main limitation is edition availability: Home editions do not include it, and organizations need the right Windows Pro or Enterprise license for the feature to be available. As long as the underlying Windows license is in place, Windows Sandbox can be used for free.
What Operating Systems Are Compatible with Windows Sandbox?
Windows Sandbox runs on Windows 10 and Windows 11, but only on supported client editions such as Pro, Enterprise, and Education. It relies on hardware‑based virtualization, so the machine also needs virtualization support enabled at the BIOS/UEFI level and compatible CPU features.
It is not available on non‑Windows operating systems and doesn’t run as a standalone product on macOS or Linux.
What Are the Alternatives to Windows Sandbox?
Sandboxie Plus is one of the closest alternatives if you want application‑level sandboxing on Windows. It lets you run individual programs inside isolated containers, keeping their changes away from your real files, registry, and system, with options for privacy‑focused boxes. Compared with Windows Sandbox, Sandboxie feels more flexible for isolating specific apps and data over time, while Windows Sandbox feels more like a disposable full desktop you open and close as needed.
VirtualBox is the well‑known open‑source alternative for running full VMs across Windows, macOS, and Linux. It supports multiple guest operating systems, snapshotting, shared folders, and virtual networking. Compared with Windows Sandbox, VirtualBox is a good option if you need persistent virtual machines or non‑Windows options, while Windows Sandbox is aimed at quick, throwaway Windows environments for testing and safety on supported Windows editions.
VMware Workstation (Windows) and Fusion (macOS) focus more on heavier virtualization. They let you create and run full virtual machines with different operating systems, take snapshots, and set up complex networking, which is useful for development, testing, and multi‑OS workflows. Compared with Windows Sandbox, VMware’s tools are more powerful and customizable but require more setup and resources, while Windows Sandbox trades flexibility for speed and simplicity inside one host OS.
