Glossary of dangerous dll files of Windows operating system

A DLL (Dynamic Link Library) is a resource that is used to run Windows operating systems and various software packages installed. These resources are very vulnerable and often subject to attacks of all kinds. Sometimes a user may accidentally delete a resource. Here is a targeted approach to some problems when calling a resource incorrect or missing. Typically replacing crush, a resource must be done in safe mode, and in some cases it may be necessary to restart the system.
