Looks like this is deprecated in Windows 8 and does nothing except return a True. There might be other side effects, but so far, it's running well for me. System reverts to 'Aero Glass' upon exit of this app. The change to Aero Basic is for Windows itself, affecting all running programs. Public static extern void DwmEnableComposition(bool bEnable) ĭwmEnableComposition(false) //DISABLE COMPOSITING - forces Windows 'Aero Glass' to revert to 'Aero Basic' 1-9-2013: so we can DISABLE COMPOSITING - forcing Windows 'Aero Glass' to revert to 'Aero Basic' Here is what I found to go to Windows Basic Colors near the start of program execution: using I had to hold the power button for 5 seconds to shut it down and then reboot. But if I minimized or maximized an MDI window before that happened, everything locked up totally. With my very graphics-intensive program, Windows Vista and 7 eventually forced the system back into Windows Basic Colors.
