“How to check which DLL is registered” refers to the process of verifying which Dynamic Link Libraries (DLLs) are currently registered on a computer system. DLLs are shared library files that contain code and resources that can be used by multiple programs simultaneously. Registering a DLL makes it available to the system and allows programs to access its functionality.
Knowing how to check which DLLs are registered is important for troubleshooting issues related to DLLs, such as missing or corrupted DLLs. Additionally, it can be helpful for understanding the dependencies of different programs and for identifying potential conflicts between DLLs.
There are several methods to check which DLLs are registered on a system. One common method is to use the Windows Registry Editor (Regedit). The Registry Editor contains a list of all registered DLLs and their associated information. Another method is to use the command prompt (cmd) with the “regsvr32 /s” command. This command displays a list of all registered DLLs along with their file paths.
1. Registry Editor
The Registry Editor is a crucial tool for managing the Windows Registry, a hierarchical database that stores configuration settings and options for the operating system, applications, and hardware devices. Within the Registry, there is a dedicated section for registered DLLs, making it a valuable resource for checking which DLLs are currently registered on the system.

Accessing the Registry Editor: To access the Registry Editor, open the Run dialog box (Windows key + R), type “regedit”, and click OK. Navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDLLs
Under this key, you will find a list of all registered DLLs along with their file paths and other associated information. - Identifying Registered DLLs: Within the SharedDLLs key, each subkey represents a registered DLL. The subkey name corresponds to the DLL’s filename (without the extension), and the default value of the subkey contains the full path to the DLL file. By examining these subkeys, you can easily identify which DLLs are registered on the system.
- Checking DLL Information: In addition to the file path, the Registry Editor also provides access to other information about the registered DLLs. By right-clicking on a DLL subkey and selecting “Permissions”, you can view the security permissions associated with the DLL. You can also view the DLL’s version information by right-clicking on the subkey and selecting “Properties”.
- Troubleshooting DLL Issues: The Registry Editor can be helpful for troubleshooting issues related to DLLs. For example, if a program is unable to load a DLL, you can check the Registry Editor to verify that the DLL is properly registered. If the DLL is not registered, you can use the regsvr32 tool to register it.
In summary, the Registry Editor is an essential tool for checking which DLLs are registered on a Windows system. By understanding how to access and interpret the information in the Registry Editor, you can effectively troubleshoot DLL-related issues and gain a deeper understanding of the system’s configuration.
2. Command Prompt
The “regsvr32 /s” command is a versatile tool for managing DLL registration on Windows systems. By leveraging the command prompt (cmd), this command provides a comprehensive listing of all registered DLLs, along with their corresponding file paths.
- Utility for System Administrators: System administrators frequently utilize the “regsvr32 /s” command to audit the system’s DLL registrations. This information is crucial for troubleshooting DLL-related issues, ensuring that critical DLLs are properly registered, and maintaining the overall stability of the system.
- Debugging and Troubleshooting: Developers and programmers find the “regsvr32 /s” command invaluable for debugging and troubleshooting DLL-related problems. By examining the list of registered DLLs, they can identify missing or corrupted DLLs, which can cause applications to malfunction or crash.
- Verifying DLL Dependencies: The “regsvr32 /s” command assists in verifying the dependencies between DLLs. Developers can use this information to ensure that their applications have access to the necessary DLLs and to identify potential conflicts between different DLL versions.
- Command Line Interface: The command line interface of the “regsvr32 /s” command makes it accessible to users who prefer a text-based environment. It allows for easy integration into scripts and batch files, enabling automation of DLL registration tasks.
In summary, the “regsvr32 /s” command is an essential tool for understanding and managing DLL registrations on Windows systems. Its versatility and ease of use make it a valuable asset for system administrators, developers, and anyone who needs to troubleshoot DLL-related issues.
3. Third-Party Tools
Third-party tools offer additional capabilities and specialized features for checking DLL registrations. These tools complement the built-in methods provided by the Registry Editor and command prompt, often providing more comprehensive and user-friendly interfaces.
For instance, Dependency Walker is a powerful tool that not only lists registered DLLs but also analyzes their dependencies. It can generate detailed reports that map out the relationships between DLLs, making it easier to identify potential conflicts and missing dependencies. This information is particularly valuable for developers and system administrators who need to ensure that applications have access to the correct DLLs and that there are no compatibility issues.
DLL Export Viewer is another useful tool that focuses specifically on displaying the exported functions and data structures within registered DLLs. This information can be helpful for understanding the functionality provided by a DLL and its compatibility with different applications. By examining the exported symbols, developers can identify potential issues and ensure that their applications can properly interact with the DLL.
The availability of third-party tools expands the options available for checking DLL registrations, providing users with a range of specialized tools tailored to their specific needs. These tools enhance the capabilities of the built-in methods and offer additional insights into the relationships and dependencies between DLLs.
