I don't want programs randomly creating shortcuts on my desktop, so I deleted everything in C:\Users\Public\Desktop and locked that folder (if I want stuff on my desktop I put it in C:\Users<my name>\Desktop).

The problem is that now when Adobe reader tries to update, it says that the update failed because it can't create a shortcut in C:\Users\Public\Desktop. But that's just the point, I don't want it to create a shortcut there. I want it to update anyway, but without creating a shortcut.

If it can't create a desktop shortcut, it should just ignore that and update anyway. Or even better, it shouldn't create a shortcut at all (if I want a shortcut I will create one manually).
