Have you ever wanted to run a suspicious program on your computer but were afraid it would harm your system? Or maybe you needed to test something without cluttering up your main Windows installation? For such cases, there is a special tool called Windows Sandbox.
Simply put, Sandbox is like a temporary, isolated room inside your computer. You can run anything in it: untested software, potentially dangerous files, or just experiment. Once you close Sandbox, all of its contents — programs, files, changes — disappear without a trace, leaving no mark on your main system.
This is a built-in Windows feature that creates a lightweight, clean copy of your operating system every time you open it. You don't need to set up a complex virtual machine or install an additional OS. By enabling it, you get a safe testing environment in just a few clicks.
Sandbox for Windows 11, 10 (eng. Windows Sandbox)
Sandbox is a lightweight Windows 10 \ 11 tool that allows you to run applications in a secure, isolated environment without fear of harming your PC.
Similar to a standard virtual machine, any software you install in the Sandbox remains isolated and cannot affect the host computer. When you close the Sandbox, all programs you installed, files you added, and settings you changed are deleted. The next time you start Sandbox, the system will return to its original, clean state. Microsoft uses hardware virtualization through a hypervisor to run a separate kernel to isolate it from the host.
This means that you can safely download an executable file from a dangerous source and install it in Sandbox without risk to your main system. Or you can quickly test a development scenario in a new copy of Windows.
It's impressive that the requirements are quite low:
- Windows 10 \ 11Pro or Enterprise
- X64 architecture
- Virtualization capabilities must be enabled in the BIOS
- At least 4 GB of RAM (8 GB recommended)
- At least 1 GB of free disk space (SSD recommended)
- At least 2 processor cores (4 cores with hyperthreading recommended)
One of the best features of Sandbox is that you don't need to download or create a virtual hard disk (VHD). Instead, Windows dynamically generates a clean snapshot of the OS based on your computer's installed system.
This makes the image incredibly light – only 100 MB. If you don't use the sandbox, the image is compressed to a tiny 25 MB. And since it's essentially a copy of your OS, you don't need a separate license key. If you have Windows 11 Pro or Windows 11 Enterprise, you have everything you need to run Sandbox.
For security purposes, Microsoft uses the container concept that it introduced earlier. The operating system in the sandbox is isolated from the host, allowing the virtual machine to run as an application.
Despite these degrees of separation, the host machine and sandbox work together. As needed, the host will recover memory from the sandbox to prevent the computer from slowing down. And the sandbox knows about your host computer's battery levels to optimize power consumption. You can run Sandbox on your laptop on the go.
All these and other improvements make it an extremely secure, fast, and inexpensive virtual system. It provides a fast and secure VM-like solution at a much lower cost than a traditional solution. You can quickly invoke, test, and reset the system state, then repeat as needed. As in all cases, better hardware will make the experience even smoother. But as shown above, even a weak PC should be able to run Sandbox.
The only drawback is that not all devices come with Windows Pro or Enterprise. If you are using Windows Home, you will not be able to use Sandbox.

The Windows Sandbox is a secure, isolated space where you can run suspicious files or programs without fear of damaging your system. If you open a virus or malware in the Sandbox, it will not be able to affect your main computer—everything stays inside the Sandbox. Enabling it is easy: you need to enable one of the Windows features (called “Windows Sandbox”), restart your computer, and then launch Sandbox itself from the Start menu. It is suitable for Windows 10 and 11, but only works on more powerful computers with virtualization support.
How to enable Windows Sandbox.
To enable Sandbox in Windows 11, follow these steps.
- Press the Win + R keys simultaneously to open the dialog box “Windows Update Center”, enter in the “Open” field:
- In the applet that opens “Windows components” all you have to do is wait for the tool to scan your system for errors related to the operation of Windows Sandbox and click “OK.”
- Restart Windows 10.
That's it! The feature is ready to use.
“Troubleshooting”
Go to the“Windows Components”, using the built-in troubleshooting tool, which automatically detects and corrects some common problems.
- ↑ Why and when should you buy used storage devices?
- Copy and paste the following command:
and press Enter. After restarting (requested during the process), Windows Sandbox will be activated.
If your Windows 11 computer refuses to shut down, don't panic right away. This problem is quite common, and in most cases, you can solve it yourself without resorting to the help of specialists. The main thing is to act consistently.
Sometimes, the main keyboard of a desktop computer breaks down at the most inopportune moment. Or you may have an old but working laptop keyboard that you want to use. The good news is that connecting it to a PC is quite a realistic task.
Now you know how to easily enable it in the system settings and run it. It only takes a couple of minutes, but it can save you a lot of time and nerves in the future by protecting your main computer from potential threats.
If the problem has appeared recently, try to remember what software you installed on your computer before that, as it may have caused the problem.
