Sandboxie Plus for PC: How to Download and Install on Windows (2026 Guide)

Every program you install can read your files, change your settings, and leave pieces of itself behind forever. Sandboxie Plus flips that around: programs run inside an isolated box, and anything they change can simply be wiped away when you are done with them.

This guide shows you how to download Sandboxie Plus for PC from its official website, install it on Windows 11 or 10, and run your first program in a sandbox. Features, system requirements, and first-use steps are covered below — plus an honest explanation of what is free and what the optional Supporter Certificate adds.

What Is Sandboxie Plus?

Sandboxie Plus is an open-source sandboxing tool for Windows, maintained by developer David Xanatos as the modern successor to the original Sandboxie. It creates an isolated container — a sandbox — in which browsers and other programs run without being able to permanently change your system.

Files a sandboxed program downloads or modifies are redirected into the sandbox folder instead of your real folders. When you close the program, you can recover the files you actually want to keep and delete everything else, returning your PC to exactly its previous state. It is a standard, sensible trick for testing unknown software and browsing more safely.

Key Features of Sandboxie Plus

Isolated sandboxes: Run browsers, installers, and untrusted programs so their changes stay inside a deletable container.
Multiple boxes: Create separate sandboxes for different jobs — one for downloads, one for testing, one for everyday browsing.
Quick recovery: Pull the files you want to keep out of the sandbox before wiping the rest, or recover automatically to chosen folders.
Snapshot manager: Save the state of a sandbox and roll back to it later (some snapshot options are supporter features).
Resource access rules: Control exactly which files, folders, and registry keys a sandboxed program may read or write.
Privacy and security box modes: Stricter box types that stop programs from reading your personal data in the first place.
Templates for common apps: Ready-made settings for popular browsers, email clients, and other everyday programs.

System Requirements

Operating System: Windows 11, 10, 8 or 7 (64-bit or 32-bit)
Processor: Any modern Intel or AMD CPU
RAM: 2 GB or more recommended
Storage: About 100 MB for the program, plus sandbox space for whatever sandboxed programs write
Display: 1024×768 or higher
Internet: Only needed for the download and optional update checks
Account: None — an optional Supporter Certificate unlocks extra features but is not required

How to Download Sandboxie Plus (Official Method)

Because Sandboxie Plus is security software, the place you get it matters. Clone download sites have been known to bundle its installer with junk you definitely do not want next to a safety tool. Download Sandboxie Plus only from its official website, where the project publishes its current releases.

Step-by-Step Installation

Open the official Sandboxie Plus downloads page linked above.
Download the latest Windows installer for Sandboxie Plus (the SandMan interface build).
Save the installer to your Downloads folder.
Double-click it and approve the Windows permission prompt — Sandboxie installs a driver and a background service.
Keep the default installation folder and the default components.
Click Install, then Finish, and let the Sandboxie service start when setup completes.
Launch Sandboxie Plus from the Start menu — the SandMan window opens, showing your default sandbox.

First-launch note: A short introductory tutorial may appear on the first run. It takes two minutes and explains recovery and deletion — the two ideas everything else in Sandboxie builds on — so it is worth reading once.

How to Run Your First Program in a Sandbox

Open Sandboxie Plus (the SandMan window) and find DefaultBox in the sandbox list.
Right-click DefaultBox and choose Run → Run Web Browser to start your default browser sandboxed — its window title shows [#] marks, confirming isolation.
Inside the sandboxed browser, download any harmless test file; it will land inside the sandbox, not your real Downloads folder.
When you close the browser, open Quick Recovery (or accept the recovery prompt) and move the file you want to keep into your real folder.
Right-click DefaultBox and choose Delete Contents to wipe everything else the session left behind.
For an installer you want to test, right-click the file in File Explorer and choose “Run Sandboxed” if that menu option was enabled during setup.

Sandboxie Plus Free vs Paid: What Is the Difference?

Here is the honest picture. Sandboxie Plus is open source, and its core job — running programs in isolated sandboxes, using multiple boxes, recovering files, and deleting sandbox contents — is free to use without any licence. For most home users testing downloads and browsing more safely, the free core is genuinely enough.

Some advanced extras in the Plus interface are reserved for users with a Supporter Certificate, a paid licence that funds the project’s development — these include certain additional box types and comfort features. The certificate does not unlock the sandboxing itself; that stays free. If you rely on Sandboxie daily, the certificate is a fair way to support the tool while gaining the extras.

Frequently Asked Questions

Is Sandboxie Plus safe to download and use?
Yes, from the official website linked above. Sandboxie Plus is an open-source project with a public development history, and the official site serves the genuine installer. Copies bundled with extras on other sites are the ones to avoid.

Is Sandboxie Plus free?
Yes, for its core purpose. Running programs in sandboxes is free; a paid Supporter Certificate unlocks certain advanced features and supports development. There is no trial clock on the free sandboxing itself.

Is Sandboxie Plus an antivirus?
No. It does not scan for or detect malware. Instead it isolates programs so their changes can be undone completely — which complements an antivirus rather than replacing one. Run both for sensible protection.

Will sandboxed programs run slower or break?
Everyday browsing and testing feel normal; very heavy file work can be slightly slower inside a box. A few programs — notably some games and anti-cheat systems — refuse to run sandboxed by design, which is a limitation of those programs, not a fault in Sandboxie.

Conclusion

Sandboxie Plus gives you an undo button for software: try things, browse, and test installers knowing nothing they do is permanent until you say so. Download it from the official website, run your browser in a box once, delete the contents, and you will immediately see why cautious users swear by it.
