How to Unregister a DLL

PC users need to unregister certain DLL files in order to either completely uninstall problematic software or to disable specific functionality from various application features. In order to unregister a DLL file it is first recommended to make sure that the application which that DLL file is associated with is not in use as in particular cases this scenario can generate several errors as well as further problematic situations.

After locating the path of the DLL file that needs to be unregistered it is required to click on the “Start” button of the operating system and click on “Run”. In the “Run” window it is required to type “cmd” and click on “Ok” in order to open a new Windows console session. With the Windows Command Console opened, it is now possible to issue operating system command line instructions. In the console, type “regsvr32 /u filename.dll”, where “filename.dll” is the DLL file that the user wishes to unregister.

While the entire process of unregistering a DLL file may seem simple at the first sight it is always risky to conduct such procedures. For this reason, it is recommended to always backup the operating system registry, system files as well as configuration before deciding to unregister one or several DLL files. In this way, in case things turn out in an unexpected way it is always possible to restore the operating system’s functionality to a previous point.
