The process rndll32.exe is implemented in relation to the operation of the graphic processing unit found on the graphics adapter. It is also related to the display properties feature used by the Microsoft Windows Operating System platform.The implementation of the file rndll32.exe is commonly observed with the installation of an NVIDIA graphics card, which is used to control and manipulate the behavior of the display interface of a computer system for various software applications. The process rndll32.exe is used to take advantage of the built-in feature of the Microsoft Windows environment in controlling a wide range of visual display options that can be accessed from the Display Properties Panel of the system.Settings and configuration procedures done under the display properties normally affect the visual styling of the entire system. It also covers how text, fonts, colors, and resolutions are reflected on the computer screen.The functional visual display as seen by the user via the computer monitor is actually a result of the combined capabilities of the monitor and the video card hardware component, which are controlled by software applications similar to the rndll32.exe process commonly bundled with the device drivers. The usage of the rndll32.exe module together with the graphic card driver allows the user to dictate the resolution settings limited by the capability of the display media including certain display properties like brightness, contrast, hue, sharpness, and other details. The implementation of the process rndll32.exe will also most likely affect how software applications are shown on the display media and how Web pages are viewed by the user.Microsoft Windows Operating System platforms come bundled with various graphic display drivers considered as generic, and these provide limited functions in terms of maximizing the full potential of the graphic display card. The importance of the computing power exerted by the video adapter comes into play when dealing with applications that require complex computations in order to accurately display images on the computer screen. This functionality can only be tapped via the supporting components of the video card like the file rndll32.exe, which allows users to fully appreciate the graphic acceleration commonly associated with computer games and other demanding applications like 3D animation and rendering.The most common instance for the usage of the rndll32.exe process is seen in gaming applications where the usage of dual monitors is becoming increasingly popular mainly because of the dropping prices of monitors and the increasing capabilities of video adapters to support them. As in the case of World of Warcraft, the rndll32.exe process is used in relation to the module nview.dll in order to create a user profile, which will modify the display either as a regular or as a widescreen feature.Using the widescreen feature allows the user to tap on the functionality of the file rndll32.exe in allowing 2 monitors to function as a single and seamless gaming console entity.
Les processus non-système tels que rndll32.exe proviennent du logiciel que vous avez installé sur votre système. À cause des nombreuses applications de stockage de données sur votre disque dur et dans votre registre système, il est probable que votre ordinateur ait subi une fragmentation et accumulé des entrées invalides pouvant affecter les performances de votre PC.

Dans Windows Task Manager, vous pouvez voir quels CPU, mémoire, disque et utilisation du réseau génèrent le processus Desktop and Window Manager. Pour accéder à Task Manager, maintenez enfoncées simultanément les touches Ctrl + Shift + Esc. Ces trois boutons se trouvent tout à gauche de votre clavier.

Ce processus est considéré comme sûr. Il n'est pas susceptible d'endommager votre système. Le fichier rndll32.exe doit être dans le dossier c:\windows\system32\. Sinon, il pourrait s’agir d’un cheval de Troie.

Ce processus n'est pas considéré comme consommateur d'UC. Toutefois, l'exécution d'un nombre trop important de processus dans votre système peut réduire les performances de votre PC. Pour réduire la surcharge du système, vous pouvez utiliser l'Utilitaire de configuration système de Microsoft (MSConfig) et le Gestionnaire des tâches pour rechercher et désactiver manuellement les processus qui se lancent au démarrage.
