Sandboxie is a proprietary sandbox-based isolation program developed by Ronen Tzur, for 32-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 the local or mapped drive. An isolated virtual environment allows controlled testing of untrusted programs and web surfing.
Sandboxie runs your programs in an isolated space which prevents them from making permanent changes to other programs and data in your computer. When you run a program on your computer, data flows from the hard disk to the program via read operations. The data is then processed and displayed, and finally flows back from the progam to the hard disk via write operations. Sandboxie changes the rules such that write operations do not make it back to your hard disk.

After downloaded, use TuneUp to change logon screen.
