Got a file you’re unsure about?
Don’t gamble — test it in a safe environment before opening.
Here’s how to use Windows Sandbox to test risky files without harming your system.
✅ 1. What is Windows Sandbox?
A lightweight, isolated virtual version of Windows:
-
No risk to your real PC
-
Auto-resets after closing
-
Great for testing
.exe,.bat,.scr, or installers
✅ Included with Windows 10/11 Pro, Enterprise editions.
✅ 2. How to enable Sandbox
-
Open Control Panel → Programs → Turn Windows features on/off
-
Check Windows Sandbox
-
Restart your computer
✅ Appears in Start menu after reboot.
✅ 3. Launch and use Sandbox
-
Open “Windows Sandbox”
-
Drag your suspicious file inside the window
-
Run and test freely
✅ Any changes stay inside the sandbox — nothing affects your main system.
✅ 4. Watch for behavior
Test file behavior:
-
Does it install unwanted software?
-
Does it access network or create new processes?
-
Does it modify settings?
✅ If anything feels shady, delete it — don’t run it on your real PC.
✅ 5. Close to erase everything
When done:
-
Simply close the Sandbox window
-
Everything resets — file gone, settings gone
✅ Like nothing ever happened.
Key points to remember
-
Windows Sandbox = disposable test system
-
Great for running risky downloads or installers
-
Everything is wiped clean after closing
-
Pro version of Windows required
-
Safer than running on your real desktop
