1. Run regedit and navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers. (If Layers doesn't exist, create it.)
2. Add a string named "C:\Directory\executable.exe" (replace this with the actual application) and give it the value "RUNASADMIN".
Apparently this can be used on Windows 8 to set explorer.exe to always run as Administrator, completely disabling UAC as with Windows 7. However, doing this will prevent Metro applications from working.
Have an application always run as Administrator.
