Hi all, I wasn't sure where to post this topic, so I hope this section is appropriate. I have a few questions: 1. I have an administrator account using Sandboxie to surf the web (default browser is firefox). On exit, I have sandboxie empty the sandbox. When I want to trial a software/install unknown software, I right click the returnil icon by the clock and click enable. This pops up a balloon stating that my c: partition is protected and changes will be lost upon reboot. Is this the idea setup? Or should I create a limited user account (where sandboxie doesn't work). Does returnil work in a limited account? I'm running Vista Home Premium SP1 2. My other question has to do with returnil. If I right click on the icon by the clock and hit enable, am I fully protected? Meaning will all changes from the point I hit enable be erased once i reboot my laptop? Is there another way I'm supposed to be doing this? When I click show program I see there is a session lock and a system protection. i am confused as to what these both are. Doe system protection being on enable the session lock to be turned on (and this is what protects my laptop?). If someone could explain the differences (or maybe they work together?) between session lock and system protection, I'd truly appreciate it.
