Hi @eimhoff  -

You can move the shortcuts from the individual user's Desktop folder to the Public Desktop folder.

I tried this with just creating a shortcut to the Windows Calculator, then I moved it to C:\Users\Public\Desktop folder. While logged into my machine as a standard user, when I choose to delete the shortcut it requires that the user have Administrative privileges' before they can complete the procedure:

In the InstallShield Editor within AdminStudio, you can open your MSI project or MST (transform) project, go to (1) Shortcuts and then right-click (2) on the Shortcuts top root node in the middle frame, and under Show Folder choose (3) [ALLUSERSPROFILE]. Then, create a new directory called "Desktop" underneath that folder and put the shortcut there. like I've done with Notepad++:

With the shortcut under this Public Desktop folder, when it gets installed it shows up under C:\Users\Public\Desktop:

This leads to the shortcut residing on the Public Desktop directory, which will block any user without admin privileges' to be able to delete it successfully.
