The Rundll32 file has the responsibility of being the data manager between what is called your dynamic link library .dll and many of the peripherals and devices attached to your computer. The Dynamic Link Library is the portion of your operating system where all the files that allow multiple programs to run at once on your Windows computer..
 

When the first Windows programs was created, it was a way for users to have a much more visually friendly interface with the DOS operating system. When a single program would run in the Windows Environment such as a word processing application, it was not able to share resources with other programs, which meant that if you tried to run three or four programs at once, the computer became bogged down because each program ran separately - and in some cases, two programs that needed access to the same file couldn’t run at the same time.
 

To solve the problem, the engineers at Microsoft came up with a way for multiple programs to share those files and resources instead of each one being a single operation. They came up with a shared library of links that would allow a running program to access the same data and files at once, and the concept of the Dynamic Link Library .dll was born.
