It is no secret that any user working with Windows of any version in Task Manager is observing the presence of the service RunDll32.exe, which is incomprehensible to many. Unfortunately, errors that occur when starting this process are not uncommon. Let us see what this process is and how to get out of the situation in emergency situations when the RunDll32 service fails.
RunDll32.exe: what is the process?
To begin with, the RunDll32.exe service is a system process that is present in any Windows OS. In simple terms, he is responsible for launching the so-called dynamic libraries, since in Windows themselves their immediate start is not provided (as it applies to executable files of the type EXE).
Analyzing questions about how the RunDll32.exe service works, what process we have in this case, and why errors occur, we can immediately say that this could be the original system process and the masking of viruses trying to gain control over any computer terminal. We will dwell on viruses later.
What are DLLs?
Dynamic libraries Libraries) are special compiled files containing executable program code. In principle, they work like ordinary "executable" files, only the EXE file is launched directly by the system or in manual mode, and dynamic libraries - using the specified service. Yes, and with Windows service It works much better than the executable EXE file.
By the way, dynamic libraries are being used more and more often lately. The fact is that, compared with a regular EXE file, they are much smaller and can belong to different programs, no matter what programming language they were created with.
Very often such libraries are used to connect software synthesizers and effects to virtual hosts. In fact, the executable program itself is absent, and each program component is invoked using the executable code that is present in dynamic libraries.
The principle of the service RunDll32.exe
As already mentioned, the RunDll32.exe service, as it were, extracts the program code from the dynamic library and runs it in the system for execution. For example, to enable the Bluetooth module developed by Motorola, the Rundll32.exe software process is also used. Btmshellex (Bluetooth Shell Extension for Windows 8) in this case is the very library from which the main program and all its related components are launched.
There are quite a few such examples. As another example, consider the help system (help) developed by NewNextDotMe. Again, runDll32.exe is used to start the service. NEngine in this case describes the New Next Helper Engine process for Windows XP, which is a unified help system.
RunDll32.exe application errors and methods for fixing them
Malfunctions and failures in this system process are quite common. Some of them can lead to a blue “screen of death” that scares regular user. In the RunDll32.exe service, an error is a very common thing, and there can be as many reasons for its occurrence. First of all, it is damage to the desired RunDll32.exe file, virus infection or just its absence on the computer.
First of all, you need to make sure that it is present in the system. In Windows XP, the original file is located along the path C: Windows \\ System32 \\ RunDll32.exe. With systems windows type 7 or 8, the situation is somewhat different. Here, the file must be searched in the SysWOW64 folder located in the Windows root directory.
If suddenly there is a warning that the system can not find this component, do not panic. For starters, you can try to find the file in folders located at C: \\ Windows \\ System32 \\ Dllcache or C: \\ Windows \\ SericePackFiles \\ i386. If it is there, you just need to copy it to the System32 folder.
You can use the original installation disk OS Windows. For example, if the drive has the letter “Z” in the designation, you will need to enter Z: \\ i386 \\ rundll32.ex_ C: \\ Windows \\ system32 \\ rundll32.exe in the command line. After restarting the computer, the problem should disappear.
In some cases, you can use another method, which consists in the fact that you first need to download the utility DLL Suite, install, and then start the application and start the scanning process for errors. If they are found, they can be fixed just by pressing a single button.
That's what's interesting. In addition to the standard scanning features, the program can offer the user to download the original RunDll32.exe file for free from an open Internet resource, after which it will be automatically integrated into the system.
RunDll32.exe: suspicion of viruses
As for viruses, it is not so simple. In order to understand whether RunDll32.exe is a virus, which process is in each specific case in the system services directory tree, you need to find out which component it is responsible for running.
For this, the standard Task Manager uses the Processes tab. Here, from the “View” menu, select the display of additional columns and tick “ Command line". Now in the process tree you will see the full path to the Rundll32.exe file, the dynamic library of the program for which it is responsible for starting, and when you hover the cursor on a line - a brief description of the process and the software manufacturer.
If for some reason the path to the file is different from the original one, and the library itself or the running process is very suspicious, it is better to complete it in the same task manager, and then apply a deep system scan with a powerful anti-virus package. Notice free antiviruses such as AVG or Avira is better not to use, they still will not find anything in most cases.
If the virus is not detected, and the error will occur again and again, you can try to check the computer using tools like the Rescue Disc from different developers. Such utilities, as a rule, start even before the launch of the Windows OS and are able to detect even the most cunningly disguised threats: malicious codes, etc.
Conclusion
So we reviewed the service RunDll32.exe. What kind of process it is, probably, is already in general clear. In addition, errors, as can be seen from the above, are not as terrible as they may seem at first. In principle, any user can correct them by applying one or several methods in turn. If you understand, any of these methods is good, but it seems that using the special utility Suite with automatic file checking and error correction in the system is the most preferable and simple.
