Embedded POS 2009.. Post installation customer config/setup.. can I do it ?

Hi,

New to embedded OS stuff so perhaps this is a basic question... hope so.

I put in the Windows XP POS Ready 2009 disk, and have created a USB boot
disk, with all the Microsoft tools/apps on it, which will of course setup my
IBM POS terminal just fine.

I will ship USB drives to our customers, who will plug this in, and install
the OS onto the POS device.

My question is after the OS has installed, I want to auto kick off my own
installer to install our in house built applications automaticlly.

Is there a way I can have my installer included onto the USB key some how so
that once the OS is installed, it will then just auto start my installer.

I need to install about 5 applications.

Hope that makes sense.
