How to Fix Rundll32.exe Errors

By Pete F Morgan

More often than not, you will encounter "rundll32.exe" whenever you use your computer and this can be seen regardless of which version of Windows you use. Some errors can be encountered with this item as well. But for us to be able to fix any errors involving it, understanding what this file is will become needed.

Rundll32.exe is an executable file responsible for running other DLL files that are present in the computer. These DLL files, or Dynamic Link Library files, are similar to "EXE", or executable, files but they cannot just run all by themselves. This special executable file is the command that makes all of these other DLL files run in the computer to get certain programs and applications to run inside it.

There are a number of issues that can happen with this kind of file. A virus can sometimes affect the way certain programs run in your computer. Problems can also cause rundll32.exe errors that trigger high CPU usage that can greatly slow down a computer. Another error that can happen is when this executable file is detected as "missing" in the computer.

How to Determine If It's A "Rundll32.Exe" Error

There are a number of ways to be able to find out if you are having any problems with this executable file. One way is to check out the Task Manager and then go to the Processes tab. If by chance you are to go there and then you see you have two instances of that executable file, it tells you that your PC has an issue with it. Running a malware scan in the PC can help in detecting it and removing the one that is a fake.

There are also instances that the computer is running slowly because of the executable file in question. The reason for this is because it has become corrupted already. When it becomes corrupted, it cannot manage the DLL files that get to run and in turn it eats up all of the computer's CPU usage, slowing it further.

5. Wait for the scan to complete and then check the message if there were any files that were fixed or any that were corrupted and were unable to get fixed.

You also have the option to download the missing file; you just have to be careful when downloading it. Some of these files are infected with a trojan so it is best to get it from trusted sources.
