[Windows 10] Sandboxing "Tiles" Applications?

Hello!

Is it even necessary to sandbox Windows 10 “Tiles” Applications considering that they’re supposed be chacked by Microsoft then also sandboxed by the OS itself?
(Or did it change from Windows 8 to 10? ITPro Today: IT News, How-Tos, Trends, Case Studies, Career Tips, More )

One “Tiles” application that got auto-sandboxed by CIS, “Daily Beautiful Pictures” or BingPics.exe, silently crashes after about a second running sandboxed - and besides the log I wouldn’t even know it was sandboxed because the green outline doesn’t show (despite that box being checked), nor a popup warning me that a program is being sandboxed (for which I actually don’t see a setting anywhere)… (EDIT : Nevermind, I remembered I got a popup the first time…)
