You can use WMI

Note the WMI example there doesn't do exactly what you want, but it should give you enough pointers (plus the MSDN WMI docs) to figure out how to do what you want.

You can also use PInvoke in C# to do some window hooks that will send a message to your application when a process is created. However this will require some C++ for the dll you inject.
