How to Get Rid of Rundll Pop Ups

1. Put a Windows operating system disk into your CD/DVD drive.
2. Hold down the key with a Windows icon on your keyboard and press 'R.'
3. Write 'cmd' in the box and click 'OK.'
4. Find out the drive letters for your CD/DVD drive and hard drive by double-clicking on the 'My Computer' icon in your desktop and having a look at which letters were assigned. If you already know your drive letters, skip this step.
5. Go back to the command line you opened when you wrote 'cmd.'
6. Write the following into the command line: expand D:\i386\rundll32.ex_ C:\windows\system32\rundll32.exe. Replace 'D' with the letter for your CD/DVD drive and 'C' with the letter for your hard drive.
