I noticed in my Microsoft Office 2016, it has the grey dotted lines, but the office 2016 at my college campus doesn't even have the grey dotted lines. It just looks so much cleaner. I'm just wondering what is going on here and what is REALLY causing that problem. There gotta be a solution.

Like for instant, I see the same grey dotted lines on my desktop icons, but when I either right click then hit refresh or hit F5, then the grey dotted lines goes away. Or sometimes restarting explorer.exe in the task manager solves the problem.

So I am assuming there is a solution to getting rid of the "focused" box, is just that y'all haven't figured out the solutions.
