Since domain-joined computers normally require a network connection to log in, the domain laptop policy will automatically cache the two most recent user logons for offline use.

Software, including the operating system, will periodically receive automatic updates that will install during a reboot when the computer is connected to the campus network. Ideally, when on campus, you should restart the computer whenever you are going to be away from it for an extended period of time (i.e. when leaving for lunch or a meeting). Not only will this ensure that your computer stays current on updates, but it will avoid any unexpected, intrusive installations.
