How to pass command-line args to my application when it has replaced Explorer.exe

I am using the techinque shown here and in a number of other places to cause my application to launch at start-up in place of Explorer (and Metro in Windows 8!) by creating a registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell

with c:\xxxxx\MyApp.exe as the argument.

This works fine but I also need to pass it some arguments. I've tried this by making my key value (for example) "c:\xxxx\MyApp.exe" "arg1, arg2" but it would appear that arguments are being taken as a possible second start-up program with the comma as a delimiter. Can anyone advise how to pass arguments to a shell substitute? I've also tried double quotes with the same effect. Is it actually possible to pass arguments in this way? Or must I create some kind of launcher app to do this indirectly? I really do want my app to be the only kid on the block....

BTW I'm using Windows 8.0 and my app is written in Delphi.

AFAIK, you'd use the parameters just like you would in a batch file:

 "C:\xxxxx\MyApp.exe" "%1" "%2" "%3" "%4" "%5"

In a batch (or the registry) the "%x" parameters have special meaning. They always mean "parameter X".
