How to unregister a dll file

A Dynamic Link Library also known as a DLL file is a type of file that contains certain information that can be used simultaneously by multiple applications. These files are responsible for a major part of Windows operating system functionality. It is important to maintain these files clean and in a certain directory if you want to retain a fully functioning personal computer.

If any of DLL files went missing or turned out to be corrupted it could lead to application failure or at times even worse, the total failure of Windows system. For instance, information contained within a DLL file could be used by your video drivers and audio drivers. If a certain DLL file was corrupted or missing, the needed codes would not reach the processes of the programs meaning that your audio and video driver would malfunction simultaneously. Thus, the paramount importance of a DLL files is quite obvious.

DLL files were introduced and implemented to reduce the usage of physical memory. If multiple applications, as mentioned earlier, use the same DLL file they reduce the usage of memory; therefore, increasing the full potential of your operating system.

Malware does not only affect DLL files, but it can also implement DLL files of its own. Dealing with corrupted or alien DLL files is a tricky business. It is important to understand that you cannot simply delete a DLL file. It is so because multiple programs may be relying on it. And the information contained within a file would be suddenly missing leading to failure of certain applications. Before deleting or editing a DLL file, you must unregister it first. After a successful un-registration, it is safe to remove or edit a DLL file.
