What is a DLL?


Your operating system comes pre-installed with Microsoft DLL’s and most third party programs also install DLL’s.

DLL (Dynamic Link Library) is Microsoft’s implementation of the shared library concept. Meaning there’s a DLL library on your computer and each DLL can be shared among different Microsoft and third party programs. This shared library method helps your computer run faster by having fewer operations running at the same time.

When a DLL is missing or corrupt it may show an error message and programs may fail or crash.

Because DLL’s are shared, one missing or corrupt DLL may affect multiple programs on your computer.
