What is rundll32.exe?
Rundll32.exe is a crucial part of Microsoft Windows that’s made to launch functionality based in Windows DLL (dynamic linked library) files. 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, so if you disable rundll32.exe then it’s possible you could cause many parts of Windows, and many Windows apps to be unable to function.
