Lock your Computer, lock your computer. That and no tailgaters. are some of the security things that are drilled into people that work at Microsoft. And for good reason. Employees, Vendors and Contractors deal with sensitive, confidential information which has not yet been released to the public.
Access to a computer could prove access to such information, so locking a computer becomes important. I have pretty much become accustomed to hitting [Windows] + [L] to do so. But sadly some of the more Junior coworkers still don't understand the hazard. So a tradition has sprang up in my team. If certain team members happen to notice that a computer was left unlocked then they will send an email from the unwary team member's computer, to everyone in the team, simply stating; "I have Stinky Feet!". Yep, quite the incentive. I have been lucky enough to not have to deal with the fallout of the resulting email taunts though I have witnessed it happening.
