In order help facilitate a secure network, I ask all my users to make sure that when they leave their desk that they "Lock" their workstation. This will usually happen when their screensaver kicks in, but not until after some preset length of time. So, my suggestion to quickly lock their workstation is to press the "Windows" key and the "L" key on the keyboard. This will immediately lock the screen. This is especially important for those users that have access to employee records, payroll, or HIPAA regulated information.
