The rundll32 file is the go for your dll files and all the peripherals, programs, and devices attached to your computer. A dll file, or dynamic link library, is a file that multiple programs utilize synchronously. For the purpose of making computers run more efficiently and use less computing resources, dll files include code that several programs may need. Programmers, instead of putting the same bit of code in every program they write call on dll files. Instead of having numerous programs with identical codes, dll files authorize you to have one copy of the code, and several programs using it. Dll files can also support background tasks that are essential to the smooth secure operation of your computer.

The rundll32 error can be caused by several unlike causes. Everything from a hardware or software conflict to viruses, worms, or Trojans can cause rundll32 errors. These error messages show up at any time something is attempting to access the dll files, like startup, loading a program or application, or shutdown. The majority of rundll32 errors are from a corrupt or missing dll file or driver somewhere that is causing another program to execute poorly.

Amending rundll32 files can be fairly simple however. Downloading and running a registry cleaner can fix the problem. The Windows registry is one of the most important parts of your operating system. It keeps data needed to almost every program on your computer, including the operating system, any attached hardware, and also holds per user settings. Any changes to your computer, such as installing or deleting software, new hardware, or a simple change in user settings affects the registry.

Typically, rundll32 errors tell you which file is missing or corrupted, but for the typical computer user, manually manipulating the registry files can be dangerous. Changes to the registry can cause more problems than you started with unless you really know what to do without question or doubt. Running a registry cleaner can fix any corrupt or fault entries in the Windows registry, and should solve the rundll32 errors.

After completing the registry cleaner scan, consider running a thorough virus scan and an anti spyware. This should eliminate any viruses, Trojans, worms, or other malicious software that may be causing the rundll32 error.
