Should I Turn Off My Computer at Night and on Weekends?

You can turn your monitor off, but do not turn your computer off. We need to apply security patches overnight so it is important that you leave your machine on.

However, you should log off of your machine at night and on weekends. You log off your machine by hitting control-alt-delete and choosing the "Log Off" option. This increases system security and allows the machine to automatically reboot if patches are applied.
