How to Remove Rundll 32

1. Locate the file 'System.ini' by searching your computer using the 'Start Search' box in the Start menu. You may also find it by looking in the C:\windows directory.
2. Right-click on the file, choose 'Open With...' and select Notepad or whichever text-editing program you prefer. If it does not show up immediately, click 'Choose Program' and select it from the list that appears.
3. Press 'Ctrl' and 'F' simultaneously to search the document for the section labeled '[boot]'. Copy and paste 'drivers=mmsystem.dll' without the quotes into the space underneath it.
4. Save and close the file, and restart the computer. This should take care of the errors you were getting. If not, you may want to contact Microsoft for further help.
