spaces to separate items in the path list, as in the following example:
\storage card\bin\ \storage card2\bin\
Launching Applications At Start-Up
The Widows CE Registry entries at key [HKLM]\init determine the
operating system programs that are started during system initialization,
and the order in which they are started. The Windows CE Platform
Builder development tool is used to establish these Registry entries.
PVPStart.exe launches Explorer during initialization, which then
handles the Window GUI, shell, taskbar, and launches the shortcuts in
\windows\startup, etc. Unlike other executable files, Windows
Explorer does not properly signal that it has completed startup, so
dependencies can not be placed directly on Explorer.exe.
Consequently, the start menu, taskbar, etc. may still be drawing when
the content of the \windows\startup folder is executed.
[HKLM]\init should be reserved for the operating system. The Shell
using shortcuts in the \Windows\Startup folder should launch
applications. The folder \windows\startup is RAM based, so its
contents will not persist from one operating session to the next. The
solution is to place shortcuts in \Storage Card\Windows\Startup. In a
normal system initialization sequence, everything in \Storage
Card\Windows\* is copied to \Windows by Postgwes.exe in the
startup order.
This copy operation is not performed when the system is in Safe
Mode.
