So we have guests coming for the weekend including teenagers. I would like to keep all sessions in virtual mode until the guests leave. Having said that, unless I'm not understanding the user guide, I can easily exclude programs from virtual sessions, e.g. Weather Pulse and Anti-Malware programs, so they can continue to update. Is this correct? Also, can I further protect my pc by keeping Sandboxie enabled (overkill I know)? Last, can I password protect or lock SS? Thank You!
