First, a little background: https://superuser.com/questions/483692/windows-3-animated-background-desktop-wallpaper was a question I had myself tried hard to answer, back when it was posted. Recently however I came across Jeff Atwood's Let’s Play The Guessing Game SE blog post. Considering that (to me) the question above (although it has a single, definitive answer) looked to be a perfect example of what Jeff was talking about, I first flagged it so a mod would decide, and when that was declined voted to close as per the mod's own suggestion. I also suggested that other questions tagged software-identification ought to be closely looked at and closed if required, and https://superuser.com/questions/375120/what-software-did-distributed-encrypted-and-shared-storage actually was.
In an extended discussion with Synetech (due apologies to him for dragging him into this), I was informed that my assumption - that Jeff's views implied an SE-wide policy to disallow "Guessing Game" type questions - was incorrect: "Identification questions are not universally shunned. For example, Arqade eventually voted to block them, but Movies/TV embraces them. SU doesn’t have a specific policy..."
So what I want to know is - how should we treat such questions here on SU?
