It is important for all computer users to have a basic understanding of how computers work, which will help in solving computer errors when they occur.  Most computer errors are related to software issues, and can be easily resolved if you know the basics of computer errors. This article is dedicated to helping computer users understand how to solve one of the most common software errors, known as DLL errors.

Dynamic Link Library or DLL files are used on a Windows system to perform certain specific tasks. These files can be shared among multiple applications and need to be loaded in the system registry only when needed.

Although DLL files are quite useful, DLL errors may cause a lot of problems on your computer and prevent you from getting any work done on the system. Here are some basics that you can use to not only fix DLL errors, but also prevent them.

The first task that you must perform as soon as a DLL error appears is to restart your PC. Quite often, the errors are generated due to a temporary conflict, which is resolved when the system is restarted.

Next, you must be careful while deleting files and folders from your PC. If you are not careful, you might delete an essential DLL file and the next time you try to use the application to which this DLL file belongs, a DLL error, such as the missing icfgnt.dll file, may be displayed. In case you delete a required DLL file, check for it in the Recycle Bin. If you find it there, restore it to resolve your error. You may also try to search for the DLL file in a legitimate online DLL directory or on another PC with a configuration similar to your system.

It is essential that you stay vigilant while installing and uninstalling programs. Overwriting or deleting essential DLL files during these processes may also result in DLL errors, such as the missing px.dll error. In case DLL errors start appearing soon after you perform any of these two tasks, reverse your action to see if the error goes away. You may also try to perform a system restore to revert your system settings and files back to the time when your PC was free from DLL errors.

You must keep your PC free from malware infections. To do this you need to have efficient virus and spyware scanner tools on your computer. You need to keep these tools updated with the latest definitions and schedule them to scan and clean your PC on a regular basis.

Finally, to prevent and fix DLL errors it is essential that you maintain a healthy and error free registry. This is vital because all DLL files need to register themselves in the registry in order to function. So, if the registry is not at its best, DLL errors may occur. One simple way of effectively detecting and fixing the registry is by using a reliable registry tool.
