	This chapter describes how to use snapins, images, change registry
	settings, install XPe software components, and set the agent mode.
Snapins
Introduction	All of HP’s thin client operating systems utilize real filesystems in
	Flash disk memory instead of monolithic Flash images. They also
	use registry-based configuration mechanisms. The combination of
	real filesystems and registry-based configuration allows HP cus-
	tomers to add software or update software modules and device con-
	figuration without having to replace the entire Flash image in the
	thin client device.
	Modular software additions and updates need only be as big as they
	have to be (and in some cases may only be a few kilobytes of
	information), and registry changes are similarly small. This speeds
	the update process and helps alleviate bandwidth impact on busy
	networks and low-bandwidth connections.
	HP provides snapins to add software to thin clients, such as Adobe
	Acrobat Reader. Snapins may also be provided by HP Technical
	Support to help diagnose customer problems. Customers can
	develop and use their own snapins, since the technology is based on
	industry-standard protocols.
