windows xp - WinXP: Difference between Log Off and Restart


Other than the obvious..


What's happening behind the scenes when you log off? Why is it necessary to restart the computer for certain configurations to take effect?



Answer



When you log off, it will close all processes and services linked to your profile, while others will remain alive. When you log back in, it restarts everything linked to your profile.


However, as implied, there are services which are running without a logged user (like for example some remote desktop servers), and these ones will remain active, and won't be restarted from log off, log back in.


Also, most things linked to hardware are initialized before log in, and they won't be changed unless you restart the computer. (Take this with caution, I'm very foggy on details, of course some hardware-related things can be changed while a session is opened). However, log off will most likely have no effect on this, for the reasons explained.
