The Desktop Window Manager in Windows 7 includes some new registry keys that are different from Windows Vista.
|
HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM |
|
(Default) |
|
AlwaysHibernateThumbnails |
|
ColorizationAfterglow |
|
ColorizationAfterglowBalance |
|
ColorizationBlurBalance |
|
ColorizationColor |
|
ColorizationColorBalance |
|
ColorizationGlassReflectionIntensity |
|
ColorizationOpaqueBlend |
|
Composition |
|
CompositionPolicy |
|
EnableAeroPeek |
Some of the settings such as ColorizationColor follow the same value format as in Windows Vista. You can use my online calculator to determine values for those settings.
Do you know what any of the other registry entries do such as Afterglow and BlurBalance? I will update this article once I have more time to research the new entries.






AlwaysHibernateThumbnails - maybe same as "Save Taskbar thumbnail previews" from Performance Options
ColorizationAfterglowBalance – changes how bright the glass is (0 removes all color from borders)
ColorizationBlurBalance – Same thing
ColorizationColorBalance – Same thing, but slightly different
ColorizationGlassReflectionIntensity – Changes how much the glass streaks are visible in window borders
ColorizationOpaqueBlend – toggle for transparency; not as good as the “Enable transparency” button in personalization.
Composition – is dwm.exe active?
CompositionPolicy – same as Composition, but the effect is reversed.
(obvious ones not included)
