Wceload tool
On a target device, the Wceload tool (Wceload.exe) is responsible for installing CAB packages. Usually, this executable is not invoked directly but rather through the shell, it being associated with the ".cab" / ".cpf" extensions on target devices.
The Wceload tool is usually included as part of the operating
system image on most devices, such as Pocket PCs, SmartPhones and even older
Handheld PC devices. This is not a general rule however, and Wceload may
not be present on some embedded, highly specialized devices. If this Windows CE
component is missing on a particular device, there is no possibility to
install CAB packages on it.
