La ventana emergente UAC proviene del software Alienware que se inicia automáticamente para administrar las características específicas de Alienware de la PC. Si actualiza el software Alienware a la versión más actual, las advertencias UAC deberían desaparecer.
To do this, the update check integrated in the Alienware Command Center didn't work for me - it insisted that the software was already at the most current version. I had to download the new version manually from the Dell support site. First you have to find your PC model under "Support for home users" -> "Drivers and downloads", then you can download software in the "Application" section. The download is called "Dell-Application" and contains the current version of the Command Center utilities.
