I've set myself up as a target at work by being big on security and "encouraging" my co-workers to lock their computers.
I've done the usual stuff, changing mouse cursor to loading indicator, their chrome icon locks their computer, screensaver BSOD etc. But now they are collectively waiting for me to leave my computer (or phone) unlocked to get me back.
I'd love to be able to leave it unlocked once or twice and prank them anyway. Or know I'd be ok if I forgot to lock it.
What are some ways I could do this? Batch files, system settings, applications? I'm a software developer so pranks that require a small application to be written would be no problem.
I have windows 7 as do most of my coworkers. Also if there's a better site for this than I can relocate but I saw the question about messing with someone's computer getting good responses.
How can I prank the pranksters, or at the very least protect my computer if I leave it unlocked?
