In the Windows Explorer, the PCMCIA Memory Card will show up as an
icon named “\Storage Card2”.
Application Run Time Environment
Path
The notion of a path to executable files is much the same as with any
other Windows or DOS system. However, unlike other systems, which
refer to an environment variable for path settings, Windows CE utilizes a
registry entry. Thus, the path can be set only by editing the value of the
registry key \HKLM\Loader\SystemPath. Note the use of spaces to
separate items in the path list, as in the following example:
“\storage card\bin\ \storage card\ \ storage card2\bin\ \storage card2\ . . .”
Launching Applications At Start-Up
The Widows CE Registry entries at key HKLM\init determine the
programs that are started during system initialization, and the order in
which they are started. The Windows CE Platform Builder development
tool (not part of the Windows CE Toolkits for Visual C++ 6.0 and Visual
Basic 6.0) is used to establish these Registry entries.

Launch90 provides a launch point at startup for an OEM that assures that
the device drivers, TCP/IP, registry and GUI functions are up and
running.
Explorer is launched during initialization because it handles the GUI
shell, taskbar, running items in \windows\startup, etc. Unlike other
executable files, Windows Explorer does not properly signal that it has
