Sandboxie is an isolation software for Windows that creates a secure virtual environment, known as sandbox, where you can run or install programs without them making permanent changes to the system.
This isolation protects the computer against unwanted modifications to files, folders, and the Windows registry, allowing you to test unknown applications, scripts, or suspicious files in a controlled manner.
Additionally, Sandboxie is widely used for safe web browsing, as all changes made during the session — such as downloads, cookies, and history — can be discarded upon closing the environment.
Due to its lightweight and efficient architecture, the software has become a reliable tool for administrators, security analysts, and advanced users looking to keep the system protected while running potentially unsafe software.
