What is a DLL and why does it run at startup?
A DLL, or Dynamic Link Library, is a type of file that contains a collection of small programs or libraries that can be used by multiple applications at the same time. DLLs are used to provide a way for different applications to share common functionality, reducing the need for duplicate code and improving system efficiency. When a DLL is set to run at startup, it means that the operating system loads the DLL into memory as soon as the computer boots up, making its functionality available to any application that needs it.
In some cases, a DLL may be set to run at startup to provide a specific service or functionality that is required by an application. However, in other cases, a DLL may be running at startup unnecessarily, consuming system resources and potentially causing problems. If you’re experiencing issues with a DLL running at startup, it’s a good idea to investigate and determine whether it’s necessary for your system.
How do I know if a DLL is running at startup?
To determine if a DLL is running at startup, you can use the Windows Task Manager or the System Configuration utility. To use the Task Manager, press the Ctrl+Shift+Esc keys simultaneously to open the Task Manager window. Click on the “Startup” tab to view a list of all the programs and services that are set to run at startup. Look for the DLL file in the list, and check its status to see if it’s running.
Alternatively, you can use the System Configuration utility to view the list of startup programs and services. To do this, press the Windows+R keys simultaneously to open the Run dialog box, type “msconfig” in the box, and press Enter. In the System Configuration window, click on the “Startup” tab to view the list of startup programs and services. Look for the DLL file in the list, and check its status to see if it’s running.
Why would I want to stop a DLL from running at startup?
There are several reasons why you might want to stop a DLL from running at startup. One reason is that the DLL may be consuming system resources, such as memory or CPU cycles, that could be better used by other applications. Another reason is that the DLL may be causing problems or conflicts with other applications or system services. Additionally, if you’ve installed an application that you no longer use, its associated DLLs may still be running at startup, wasting system resources.
By stopping a DLL from running at startup, you can free up system resources, improve system performance, and reduce the risk of conflicts or problems. Additionally, stopping unnecessary DLLs from running at startup can help to improve system security by reducing the attack surface.
How do I stop a DLL from running at startup using the Task Manager?

It does not uninstall the DLL or remove it from the system. If you want to completely remove the DLL from the system, you’ll need to use a different method.
What are the risks of stopping a DLL from running at startup?
Stopping a DLL from running at startup can have unintended consequences, depending on the specific DLL and its purpose. If the DLL provides critical functionality for an application or system service, stopping it from running at startup may cause problems or errors. Additionally, some DLLs may be required for system stability or security, and stopping them from running at startup may compromise the system.
Before stopping a DLL from running at startup, it’s essential to research the DLL and its purpose to ensure that it’s safe to do so. You can use online resources or consult with a system administrator or IT professional to determine the potential risks and consequences of stopping a DLL from running at startup.
How do I remove a DLL from the system completely?
To remove a DLL from the system completely, you’ll need to use a different method than simply stopping it from running at startup. One way to remove a DLL is to use the Windows uninstaller to remove the application or program that installed the DLL. Alternatively, you can use a third-party utility or registry cleaner to remove the DLL and its associated registry entries.
However, be cautious when removing DLLs from the system, as this can potentially cause problems or errors if the DLL is required by other applications or system services. Before removing a DLL, make sure you’ve researched its purpose and ensured that it’s safe to do so.
