The question: Where is the "All Users" folder for pinned Start Page Tiles in Windows 8?
The short answer:
There is not an exposed location for this.

I think Microsoft is in a little trouble here: There is no mechanism for an all-users start tile because, by definition, how the Start Page is organized and grouped is a user-specific preference. An all-user tile arriving in the middle would interfere with that user's preferences. There is no doubt this hurts in a corporate environment.
Finding a Start Tile's location:
A Start Tile's location can be found with these steps:
1. From the Start page, "other-mouse-click" (right mouse) the tile to
select. Illustrated below, note the Firefox icon with a check in the
2. From the bottom context menu, choose "Open File Location"
Microsoft Installed Tiles are stored here (think "All Users"):
But if you try to pin any program to the Start Page, it arrives here:
C:\Users\(your ID)\AppData\Roaming\Microsoft\Windows\Start Menu\Programs
No matter how hard you try, you cannot point a pinned icon to the ("All Users") location.
The issue is this: If an administrator installs a program and builds a Start Tile; then logs out, other users will not see the Start Tile. They would have to build their own. I am still looking for a solution to this problem. As of Windows 8.1, this is still an issue.
