[vox-tech] Disturbing XP Error Message

[Robert G. Scofield]

My son runs Windows XP.   He is home for the summer.  During the school year 
his laptop has been connected to the U.C. Santa Cruz dorm "Resnet" system.  
At home his laptop is in his room where he has a wireless connection to the 
Internet by way of a router.

Recently he has been getting this very disturbing error message when he shuts 
off his computer:

"Other people are logged on this computer.  Shutting down Windows might cause 
them to lose data.  Do you wish to continue?"

He says that he is not connected to any file sharing programs or computers.  
I've heard that XP itself spies on its users.  Does anybody have an idea of 
what's going on here?

Thank you.

Bob
