ListDLLs

ListDLLs is a lightweight, command line utility that has the role of displaying the DLL files that are associated with current running processes. According to the developer, the application can list all the DLL files loaded into all processes as well as the ones loaded in a specific process. Moreover, users can also select all processes that require a particular DLL file to be loaded.
As far as the information displayed is concerned, the utility can display detailed information about the DLL files, including here their full version, digital signature and PID. What makes the tool stand out is that it can also scan processes for unsigned DLL and it can flag loaded files that have a different version number than the one shown on the corresponding on-disk files. The later situation should not be alarming, as this can occur if the file is updated after the program starts and loads the DLL files.
The application can come in handy for users who want to update the DLL libraries, perhaps because the processes or programs that are using it are nor working properly. At the same time, the tool may be useful when attempting to delete a DLL, but the OS does not allow you because it is locked to a process that is using it.
