just to clarify 1 thing, they're exactly the same on every install, it really depends on your video hardware. for example mine (gigabyte 9600 pro) is "{A9707A3D-0C3C-4214-AEE3-A771F23C7CB6}".for what i know, at the moment, there is no way to apply video aceleration to all the devices... i've seen you've missing some (these are from my particular reg file)... ;directx acceleration [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Direct3D\Drivers] "SoftwareOnly"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectDraw] "EmulationOnly"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectDraw] "DisableAGPSupport"=dword:00000000 ;acceleration level for audio [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\Current\System\CurrentControlSet\Enum\PCI\VEN_1102&DEV_0004&SUBSYS_10071102&REV_04\4&3B1D9AB8&0&3840\DirectSound\Mixer Defaults] "Acceleration"=dword:00000000this last depends on your hardware too. ;Start Themes Service [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Themes] "Start"=dword:00000002 ;Disable Manage Server Roles screen [HKEY_USERS\.DEFAULT\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Setup\Welcome] "srvwiz"=dword:00000001 [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Setup\Welcome] "srvwiz"=dword:00000001 ;optimize memory for programs [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "LargeSystemCache"=dword:00000000 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl] "Win32PrioritySeparation"=dword:00000026
