IS rundll32.exe required to run windows 11

Question

A recent are5ticle I read talks about rundll32.exe and labels it a necessary and integral part of Windows (11). It mentions how it can sometimes be used for malware, and tell os an app called "Process Explorer" to check on rundll32.exe and what processes are using it. It implied that one will alwasy find at least on instance of it running, but on my functioning Windows 11 system, there are NO instances of rundll32.exe present. Is this an error? Should I always see an instance? Or is what I (don't) see actually normal?

Answer 1

Hello， Thank you for posting in our Q&A forum. It is not an error that there is no instance of rundll32.exe on the windows11 system. For example if you’re using a Windows app that needs a DLL rundll32.exe will make it possible for that app to use the DLL it needs to operate. A Windows DLL library contains code that can be used by more than one program at a time on Windows.
