On another page I discuss the general considerations of using Rundll32.exe and give specific examples for Windows XP. Here I give examples for Windows Vista and Windows 7.

Syntax for using commands with rundll32.exe

Although many of the commands with rundll32.exe that work in Windows XP still hold, there are numerous differences. Because of the large number of commands, there are no simple general rules about which commands exist. However, here are listed some that are more likely to be useful in daily use.
