Does windows (specifically Windows XP) use a registry key value to 
execute the following command from a program?

   ShellExecute(0,"open","http://finance.yahoo.com","","",SW_SHOWNORMAL);

If yes, what is the name of this key?

Yes.  It has to look up the program that is registered to handle the
HTTP protocol.

It is not a single key, but several keys working together.  The Shell
recognizes that the specified filename begins with a URL protocol, so
it first opens the following key:

    HKEY_CLASSES_ROOT\<protocol> (in this case, <protocol> is "http")

It checks if the key has a "URL Protocol" value present.  If present,
it then checks if the following key exists:

    HKEY_CLASSES_ROOT\<protocol>\shell\<verb> (in this case, <verb> is
"open")

If it does, then the Shell executes the program specified in the
"command" subkey, or connects to the server specified in the "ddeexec'
subkey.

Refer to the following article for more details:

    Registering an Application to a URL Protocol

I use SeaMonkey as my default browser and when I upgraded from version 
1.1 to 1.1.1 the ShellExecute command show above returned 
SE_ERR_NOASSOC.  Evidently the upgrade trashed the associations in the 
registry.  I guess I will rebuild them from another machine that has 
SeaMonkey installed as the default browser unless you can suggest an 
easier way.

Then SeaMonkey is not registered as the default browser correctly.
