windows host process rundll32 has stopped working outlook 2016.

Do you keep getting the error “Windows Host Process (Rundll32) has stopped working” when using Windows 10? This error most often appears when you try to open or interact with certain programs – native or third-party – on your computer. But he can also harass you randomly for no apparent reason. Why is this happening?

Windows 10 uses the Rundll32 process to execute 32-bit DLL (dynamic link library) files. These files contain functions that are common to several applications. However, conflicting software, misconfigured settings, or corrupted system files can cause Rundll32 to fail, hence the cause of the error.

The “Rundll32 Has Stopped Working” error has been troubling Windows users for years, but there are several fixes that can help you get rid of it. We recommend using the following troubleshooting methods in the order in which they appear. Feel free to skip the ones that don’t suit you.

Run File and Folder Troubleshooter

If File Explorer still displays the “Rundll32 is not working” error despite turning off thumbnail previews, try running the Files and Folders troubleshooter.

1. Download the Files and Folders Troubleshooter from Microsoft.

2. Open the Files and Folders Troubleshooter – you do not need to install it.

3. Select Advanced, select the Apply fix automatically check box (if it is not already selected), and click Next.

4. Select all the options on the “What problems are you experiencing” screen and click “Next”.

5. Follow the instructions on the screen to fix any problems found by the file and folder troubleshooter.

Update, Reinstall, or Uninstall Programs

Did you get a problem after installing a certain application on your computer? For example, programs such as Nero and the K-Lite Codec Pack have generated “Rundll32 not working” errors in the past.

If so, try updating or reinstalling the program. If that doesn’t work, you can completely remove it from your computer.

Disable Services and Startup Programs

Third-party background services and launchers can also cause Rundll32 error. Check if disabling these tools helps. Then you can go through the elimination procedure to find out which element is causing the problem.

Disable Third-Party Services – System Configuration

1. Press Windows + R to open the Run window. Then enter MSConfig and click OK.

2. Go to the Services tab. Then select the Hide all Microsoft services check box (this will only show third-party services) and select Disable all.

3. Select Apply and then OK to save your changes. When prompted, select Exit Without Restarting.

Disable startup programs – Task Manager

1. Right-click the taskbar and select Task Manager.

2. Select “Details”.

3. Click on the Startup tab

4. Select each third-party launcher and click Disable.

5. Close the task manager.

Reboot your computer. If the Rundll32 error no longer appears, start re-enabling multiple services and startup programs at once. This should help you identify the problematic item. Then you can update the corresponding program or uninstall it from your computer.

Roll Back Audio/Video Drivers

The “Rundll32 has stopped working” error can occur after updating the audio or video drivers. For example, Realtek, Sound Blaster, and NVIDIA drivers can cause this on rare occasions. To roll them back, use Device Manager in Windows 10.

1. Right-click the Start button and select Device Manager.

2. Expand Sound, video, and game controllers.

3. Right-click the sound driver and select Properties.

4. Click the Driver tab and select Roll Back Driver. Repeat these steps for all other drivers in the list.

5. Expand the Display Adapters section in Device Manager and repeat steps 3 and 4.

Update Audio/Video Drivers

If rolling back your audio and video drivers didn’t help (or if you weren’t able to roll them back before), try updating them.

1. Open Device Manager.

2. Expand Sound, video, and game controllers.

3. Right-click the audio driver and select Update Driver.

4. Select “Search automatically for drivers” to search and automatically apply the latest drivers. Repeat these steps for all other drivers in the list.

5. Expand the Display Adapters section and repeat steps 3 and 4.

Alternatively, you can download the latest audio or video drivers directly from the manufacturer’s website and manually update them.

Update Windows 10

An outdated version of Windows 10 can cause all kinds of problems. If you haven’t updated your computer in a while, try it now.

1. Open the “Start” menu, type “Windows update” and select “Open.”

2. Select Check for Updates.

3. Install all updates, if any.

Disable Data Execution Prevention

Data Execution Prevention (DEP) is a Windows 10 feature that monitors and protects system memory from malicious attacks. However, this can prevent the Rundll32 process from working properly. Check if disabling DEP helps.

1. Open the Start menu, enter Command Prompt, and select Run as administrator.

2. Copy and paste the following command into an elevated command prompt console:

bcdedit.exe / set {current} nx AlwaysOff

3. Press Enter to disable DEP.

Did this fix the “Rundll32 has stopped working” error? If so, you can still continue with the rest of the fixes, as disabling DEP is a security risk.

Note. To enable Data Execution Prevention later, run the following command in an elevated command prompt:

bcdedit.exe / set {current} nx AlwaysOn

Scan for Malware

Malware can disguise itself as DLL files and end up causing the “Rundll32 has stopped working” error. Try using Windows security to scan your computer for malware.

1. Open the Start menu, type Windows security, and select “Open.”

2. Select Virus and threat protection.

3. Select “Scan Options”.

4. Select Full Check. Then select Scan Now.

If Windows Security has failed to dig something up, we recommend using a malware removal tool like Malwarebytes to thoroughly clean your computer.

Run an SFC Scan

The SFC (System File Checker) scan can detect and repair corrupted system files that are preventing the Rundll32 process from working as expected.

1. Open the Start menu, enter Command Prompt, and select Run as administrator.

2. Enter the following command:

SFC / scannow

3. Press Enter.

The SFC scan may take several minutes.

Run a DISM Scan

If the SFC scan fails to find and fix any issues, run DISM (Deployment Image Servicing and Management) scan.

1. Open the Start menu, enter Command Prompt, and select Run as administrator.

2. Run the following command:

DISM / Online / Cleanup-Image / CheckHealth

3. If DISM detects problems on your computer, run the following commands one after the other.

DISM / Online / Cleanup-Image / ScanHealth

DISM / Online / Cleanup-Image / RestoreHealth

What Else Can You Do?

If none of the above fixes resolved the Windows Host Process (Rundll32) has stopped working error, you can reset Windows 10 to factory settings by going to Start> Settings> Update and Security> Recovery. You can choose between keeping or deleting files and programs during the reset procedure.

You can also try reinstalling Windows 10. This can be a serious problem that only a complete reinstallation of the operating system can fix. Just remember to create a full backup of your data beforehand.
