Most people who work in a network environment log onto their computer every morning and log off every evening before leaving for the day. In these environments, employees are reminded not to leave their computers unattended while logged on. Anyone could access your computer and wreak havoc using your credentials. This could be anything from creating problems on the network to sending emails posing as you get to proprietary information, and even deleting important documents.
The fastest and best way to lock your computer is to press the Windows button (located at the bottom left of your keyboard) and the letter “L” at the same time. You will get a blank screen and then the message: “This computer is in use and has been locked by (Username).” It’s a quick easy process to lock and secure your computer. To unlock it again, press Esc and enter your password to go back to work.
