The CEO of my company has a 60" display behind his desk. At any moment he wants to display a quote, picture, or whatever else on the screen. His skills are limited, but he is pretty good with powerpoint. The simplest way I could come up with was that he could drop his powerpoint slide into a shared folder, and either click something to trigger the update on the remote computer, or the remote computer would monitor the shared folder for new files, and update it then.
I had no luck with scheduled tasks running a batch file (either it wouldn't run again if it was already running, or the command window would flash on the screen every 5 minutes) and I thought some kind of script might work better.
