When you finish working on your computer, you need to make sure to turn off, or shut down, your computer properly. This involves several steps: saving and closing all open files, closing all open windows, exiting all running programs, shutting down Windows itself, and finally, turning off the computer. However, if you shut down your computer before or while installing Windows updates (download must be complete), Windows will automatically complete the install before shutting down, so you don’t have to wait around. Shutting down your computer makes sure Windows and all its related programs are properly closed; this avoids potential problems starting and working with Windows in the future. If you turn off the computer by pushing the power switch while Windows or other programs are running, you could lose important data.
