In the Properties, Compatibility (or Shortcut) tab I have ticked the "Run as administrator" box for certain applications that need administrator privileges.
When I then run these applications Windows still shows me the UAC prompt (eg: Do you want to let this program make changes to your computer?).
Why am I still asked this question after I have explicitly told Windows to always run the program as Administrator?
I realize I can turn the UAC prompt level down so that I no longer see any prompts, however the UAC prompt is still valuable for new or unknown programs, so I do not want prompts completely disabled.
For programs that I trust, it is just an annoying distraction.
(I'm also familiar with the creating a task in the scheduler with highest privileges, but that doesn't answer the question as to why UAC still prompts even when Run as Administrator is set.)

This is by design. The checkbox negates the need to right-click and select "Run as administrator" every time.
Windows requires authentication for any task that requires administrator privilages. By what you suggest, nothing would prevent malware searching your computer for "Run as administrator" icons, running them, then using the application to access the depths of your file system. If the program ever displays so much as a file dialog, immediately the malware could modify files in restricted areas of the system.
