How to Get Rid of a Run.dll Error on Startup

By Jim Campbell

Rundll.exe is a file embedded into the Windows operating system that executes code on your computer. It is often placed in the Windows "Startup" procedure to load applications into memory each time you start your computer. The "MS Config" utility contains each startup program that runs when you boot. Using the MS Config utility, you can stop a Rundll.exe error from showing each time you boot your machine.

Step 1

Click the Windows "Start" button and type "msconfig" into the text box. Press "Enter" to open the window. If you are using an older Windows version, click "Start" and then select "Run." Enter "msconfig" and press "Enter."

Step 2

Click the "Startup" button. This opens a list of applications that run each time you start your machine. The check boxes are used to enable and disable the startup applications.

Step 3

Remove the check mark in the box labeled with "Rundll." Click "OK" to save the changes. A popup appears with the option to reboot your computer. Click "Restart" to reboot your computer. The next time it boots, the rundll error will not occur.
