Pocket PC is a hardware specification created by Microsoft Corporation.
Devices that wish to carry the Pocket PC logo must meet the minimum
hardware requirements set in the Pocket PC specification. Manufacturers
are free to add extra hardware functionality.
Pocket PC 2002 devices also use a specialized version of the CE operating
system. This OS is built from Windows CE 3.0 but contains customiza-
tions, most notably the lack of a desktop and the addition of the Today
Screen.
To carry the Pocket PC logo, all devices must be tested at an Independent
Test Laboratory. The ITL testing is done based on Microsoft require-
ments. The test lab then reports the findings back to Microsoft Corpora-
tion and Intermec Technologies. If the 700 Series Computer passed all
tests, Intermec is allowed to ship the device with the Pocket PC logo. Each
time the operating system is modified, Intermec must resubmit to ITL
testing.
This means we cannot change the operating system much and still be a
Pocket PC device. For example, if we remove Word from the Start menu,
the device would fail ITL testing and we would not be able to ship devices
with the Pocket PC logo.
Although many customers want a Pocket PC device, some customers
would prefer that their users not have access to all of the Pocket PC featu-
res. Intermec cannot customize the operating system in any way but a cus-
tom application can:
S Delete items from the Start menu, and Programs folder. These items are
just shortcuts in the file system so the application is not really being
deleted. Cold booting the device will bring these items back so the ap-
plication will need to be run on every cold boot.
S Use the RegFlushKey() API to save a copy of the registry to a storage
device. See the Recovery CD Help for more information on how to do
this. Saving a copy of the registry will allow most system settings to be
restored in a cold boot situation.
S Use the SHFullScreen() API in conjunction with other APIs to make
the application take up the entire display and prevent the start menu
from being available.
S Remap keys and disable keys on the keypad.
S Create a custom SIP.
S Make changes to the registry to configure the device.
