A DLL file is a core part of the windows operating system, these are shared program files, dll files actually mean Dynamic Link Libraries and are very important for your computer. When you first install windows a large number of important DLL files will be installed along with it to ensure it runs correctly.
What is a dll file for?
The idea of a dll file is actually a fairly simple one, you see computer programs will all at some time need to use the same code that other programs use. Therefore instead of putting all of this code into the program itself it references a dll file. Numerous programs can access the same dll file to get the same code, in other words it saves you space on your hard drive. Not only this but it will also reduce the amount of memory required to run similar applications at the same time.
What's the problem with Dll files?
If this all works properly then there isn't a problem, however is there is a missing dll file, or a dll file becomes corrupt then it can wreak havoc with your system. This will result in your computer displaying lots of missing dll file error messages and possibly even cause it to crash.
So how can you lose a dll file? Well it's actually quite easy, if you install another application which also has the same dll included then this could overwrite the original. This could mean that the version you install will not be recognized by your existing programs. Even if it is should you wish to uninstall the program then it could end up removing this dll file which in turn will stop your system running properly.
How to fix these dll errors
DLL errors are easiest to fix by using a registry scanner such as Regcure, this is an excellent piece of software which can be downloaded here. It can be very confusing for many computer users to fix their registry, however it is an important task that you need to do. By using these registry scanners the whole process is automated and means that you don't have to worry about the technicalities of what you are doing. You should however make sure that you back up your registry just in case.
Your windows registry contains all of the settings which are required for your computer to run properly and control its hardware. It is accessed every time you run an application to check exactly what should be done, and all the settings are controlled using the registry.
Your windows registry will include links to dll files, if these files are missing or corrupt themselves then it can cause problems when your computer tries to find them. It may be possible to resolve the problem by correcting the registry entry.
There is another way to correct the file, when windows boots up it will commonly tell you if it can't access a specific file. If this is the case then you can put this name into a search engine to find the file and then downloading it. If you put it in the right directory then this will work wonders, assuming of course you're using a compatible version.
Trojans and viruses are also well known at causing errors with your dll files, this could cause them to become corrupt or simply remove them. You must be careful when scanning for viruses that if you delete an infected dll file you may have to replace it later.
What damage can the windows registry cause
A corrupt windows registry can cause all sorts of problems which could result in your computer crashing and going to the dreaded blue screen of death. As we've already mentioned you can use registry scanning software to fix the registry.
As well as dll errors, a problem with the windows registry can cause the following problems:
- Runtime Errors
- Executable errors
- ActiveX Error
- General Protection Fault
- Internet Explorer Error
- System 32 Error
- Access Violation
- Windows Installer Error

If you've ever seen the blue screen of death, which is a blue screen detailing the fault filled with loads of numbers which nobody understands then there is no getting back without restarting your system. This is an extremely annoying error as it can happen at any time without warning.
