When you create an input method editor (IME), or when you port an IME between Windows Mobile Standard and Windows Mobile Classic, you may have to customize the HKEY_LOCAL_MACHINE\SYSTEM\Ime\Settingsregistry key to get the desired behavior in edit controls. This is particularly likely in use cases such as focus switching, and ensuring that the final character input into a password edit control is included in the composition string.
The HKEY_LOCAL_MACHINE\SYSTEM\Ime\Settingsregistry key is used to determine the behavior of an IME. The Settingskey's value represents the following structure, where the first member is the lowest bit.

struct {
bool m_CompositionStringGetExcluded:1;
bool m_CompositionStringSetExcluded:1;
bool m_DetermineOnLossOfFocus:1;
bool m_CandidateOnKeyUp:1;
bool m_UnderlineCompositionString:1;
bool m_CancelOnBufferFull:1;

The following table describes the role of each of the structure's members.
