[WINCE]
use_systray=1
By default the DP4 Service tries to run as a task that is displayed in the taskbar notification area (or system tray). However, on some versions of Windows CE there is no facility to actually display this area, and the DP4 service is therefore not visible as a task. If this value is set to 0 then DP4 system will appear as an ordinary task (so it will show up in the list of running programs on Pocket PC for example).
