This is an awesome prank. What you see here is the Windows desktop that Redditor Croft1342 was greeted with after having a friend repair his computer. Jigsaw from the Saw movies is such a jerk. Only one of those Chrome icons is actually Chrome.
The rest? All of those are Internet Explorer. That’s just downright mean, but funny as hell. We don’t know if Croft knew how to solve the riddle or if he was able to, without going through each icon individually. Man, that would take some time. I bet he wasn’t laughing.
Of course all you have to do is put a new icon on the desktop, but sometimes it is the simple answers that elude you.
