A dll file contains code and other instructions that can be shared among multiple programs. Many programs use dll files to lighten the memory load of their code, because dll files can be loaded into memory when they are needed instead of always taking up some portion of your computer’s memory. The registry tracks these files for Windows, and an error in the registry will mean that programs will not run.
