Many happy days working with WinCE - kernel. It´s realy interesting world - remembering me Windows NT or DOS. First try to modify it, if WinCE still alive, try to add something. WinCE exprorer is the part of navigation, when you switch off navigation
program, only WinCE are still running, it gives you (Control Panel) basic information about limited structure of WinCE running on this device.
