Windows 10: Process host windows Rundll32

Hello,

I'm having some trouble with updating and uninstalling programs on my PC with Windows 10 as lately a message occur telling me that "Process host windows rundll32" is running and therefore I cannot update/uninstall the program. I've already searched on internet to try and resolve this problem but can't seem to find a solution.

Any help would be appreciated!

Thank you!

:)

That is certainly not normal, you will need to find out what processes are running on rundll32.exe

Rundll32 is just a host for other processes to run, to find out exactly what is running on this process, Click HERE to download the free ProcessExplorer

The app will download in a zip file (approx 1.84mb), unzip it and run the appropriate version (32bit or 64bit) for your system by right clicking the exe and choosing 'Run as Administrator'

You’ll want to choose File - Show Details for All Processes to make sure that you’re seeing everything

Hover over the rundll32.exe in the list, you’ll see a tooltip with the details of what it actually is:





Alternatively you can right-click, choose Properties

Ran all of the above malware removal tools for Windows 10. "Windows host process (Rundll32) has stopped working" error message only occurs when I try to view jpegs in Windows Photo Viewer. How can I restore my ability to view jpegs?

 

Windows Host Process (Rundll32) - Multiple versions

Running Windows 10 and experienced a slow down in processing tasks. I checked in File Manager and found I have 4 versions of Windows Host Process (Rundll32) active. 3 of them show memory and CPU usage and 1 seems to be static. Checked the library paths
and all 4 reside in System 32 library. Do I need 4 versions or can I stop 3 of them.
