Sandboxie is a sandbox-based isolation software for 32-bit and 64-bit Windows NT-based operating systems. It creates a sandbox-like isolated operating environment in which applications can be run or installed without permanently modifying local & mapped drives or the Windows registry. An isolated virtual environment allows controlled testing of untrusted programs and web surfing.Sandboxie allows you to create virtually unlimited sandboxes and run them alone or simultaneously to isolate programs from the host and each other, while also allowing you to run as many programs simultaneously in a single box as you wish.
