Sandboxie is awesome! Espically the registered version. Run multiple sandboxes at one time, force programs and even folders to always run in a sandbox! Really good to all the places you download applications to. That way you never forget to run it sandboxed.

Fast, pretty easy to use, always kept updated, problems fixed fast, and some of the best security you can get right now when sandboxie is setup correctly!
