Quote - The logistics of switching OS is not that simple.  Security protocols must be scrutized, changed or rewritten to protect sensitive information (I work at a hospital facility; we are bound by HIPPA regulations).  Individual profiles can be set on multi-user computers but access is strictly controlled by login/logout protocols; I can't leave programs running if another user wishes to use the computer.  Fortunately, my work computer is only used by myself.

I get what you're saying, but I'm a security guard at my job. For the most part we all use the same programs. In fact, before all this individual log-in began we simply left the computer on all day with one login. I'm simply guessing here that the guards are being spied on to see who's doing what and when. It's not like it would be the first time. As I said, we all use the same program, but one one person logs out, he has to shut down that program and the next person has to start it up again.
