Windows Sandbox is a built‑in Windows feature that lets you open files in a temporary, isolated Windows environment. Anything you do inside the Sandbox disappears the moment you close it.

Think of it as a disposable PC inside your PC.

This is extremely useful for:

• Testing unknown files or installers
• Opening macros-enabled Excel files from external sources
• Verifying scripts or tools before using them on your real system

No virtual machine setup. No third‑party tools. Just open, test, close—done.

✅ Benefits

• Protects your main system from malware or risky files
• No permanent changes to your PC
• Faster and simpler than full virtual machines
• Ideal for IT staff, analysts, and power users

🛠️ Procedure

1. Enable Windows Sandbox

• Open Windows Features
• Check Windows Sandbox
• Restart your PC (one-time setup)

2. Launch Windows Sandbox

• Press Start → Search Windows Sandbox
• A clean Windows desktop opens in seconds

3. Test files safely

• Drag and drop the file into Sandbox
• Open or run it as needed
• Close Sandbox when done (everything is deleted automatically)

📎 Notes

Available on Windows 11 Pro, Enterprise, and Education editions.

Sandbox resets every time—save nothing you want to keep.

Perfect companion to antivirus, not a replacement.
