It is the DLL [Dynamic Link Library] loader. A system will not function correctly without this DLL present.

Rundll loads and runs 16-bit DLLs, whereas Rundll32 loads and runs 32-bit DLLs.

If you pass the wrong type of DLL to Rundll or Rundll32, it may fail to run without indicating any error messages.

If it's in startup, it's probably to load either the QuickRes utility or power profiles.

QuickRes (shown as TaskBar Display Controls) allows you to change the screen resolution and color depth using an icon in the System Tray, and power profiles (Shown as LoadPowerProfile in MSConfig) load the power management settings for the machine and the user (hence shown twice in MSConfig)
