In plain English

Sandboxie is a Windows security tool that runs programs inside an isolated environment called a sandbox. When a program runs inside Sandboxie, any changes it makes, to files on disk or to the Windows registry, are captured in a contained area and do not affect the rest of the operating system. This makes it safe to run untrusted programs or browse the web without risk of permanent changes or infection spreading to the host system. When finished, the sandbox contents can be discarded. The software is available in two editions. Sandboxie Plus has a modern interface and supports a long list of additional features, including snapshot management (saving and restoring sandbox states), a per-sandbox network firewall, privacy-protected sandboxes, limits on memory usage, encrypted sandboxes, DNS control, and the ability to route a sandboxed process's traffic through a proxy. Sandboxie Classic retains the older interface and does not expose these newer capabilities through its UI. The project is a community-maintained fork that became open source after the original developer released the source code. It runs on Windows 7 and later (64-bit). The readme notes this is a community fork and not the official continuation of the pre-open-source development.
