Timer Driver Registry Settings (Windows Embedded CE 6.0)
1/6/2010
You can control the thread priority of TimerThread by using the registry key under HKEY_LOCAL_MACHINE\SYSTEM\MMTIMER\Priority256. By default, Priority256 is set to THREAD_PRIORITY_TIME_CRITICAL.
The priority that the application can assign to TimerThread** varies depending on whether an application is trusted or untrusted. Trusted applications have access to more thread priorities. Untrusted applications have access only to a specified range of priorities. For more information on priority levels, see Real-Time Priority System Levels. Trusted applications use CeSetThreadPriority to set thread priorities and untrusted applications use SetThreadPriority. For more information about creating a trusted environment, see Trusted Environment Creation.**
