OpenPHT doesn't seem to properly support the Windows Away-Mode, which has been a part of Windows since XP. This basically breaks the CEC functionality in Windows:
When Windows tries to wake system for background tasks (for example scheduled Windows Update or a tv recording), OpenPHT doesn't recognize the away-mode call and overrides it.
Instead of the system remaining "silent", OpenPHT incorrectly sends a CEC command and wakes up connected TV and AVR.
OpenPHT needs to register to receive away-mode status:
The powermanager then needs to check for the Away-Mode call like this:
case PBT_POWERSETTINGCHANGE:
{
POWERBROADCAST_SETTING* s = (POWERBROADCAST_SETTING*)nEventData;
if( s != NULL && IsEqualGUID( s->PowerSetting, GUID_SYSTEM_AWAYMODE ) )
// The computer is entering "away" mode.
