What I concluded after fixing the Store displaying the 1 next to the arrow when there was no apparent application that required an update was that there was actually an update that needed to be downloaded and applied. In my case, Windows updates downloaded something called Store purchase app after setting automatic updates for Store apps back to On and rebooting,
After that update, my Store application showed that Store was indeed modified on August 3. I have no idea what the Store icon looked like 5 days ago as I don't use Store or place the icon in my taskbar but I just placed it there now to see what it looks like and post this picture so you guys can compare. My feeling is that if you saw the icon changing, is because an update was applied when you did the registry fix and thats why the 1 went away in that computer.
My Store continues fixed. I opened it a few minutes ago, it shows an update pending for Photos and a 1 next to the arrow.
