Desktop Window Manager

WindowBlinds

from WinCustomize Forums

Question:  Does one NEED to allow Desktop Window Manager to run under Vista whenWindowBlinds does basically the same thing?  With WindowBlinds active and switching off DWM through the task manager, I notice no difference after the screen winks out and returns.  DWM uses so much computer resources vs. WindowBlinds 6.3.  Is it absolutely necessary to allow this resource hog to run?

I believe that DWM is necessary for most of Vista's special effects: blurred transparency (idk if windowblinds uses its own method to do that now), window animations/transitions, win key + tab 3d window switching, dreamscene (maybe?), window previewing (when hovering over taskbar items), etc. If you don't need or use these things, then I don't think there's any problem with disabling DWM although it may break some programs that use it. In fact, you can't run DWM without a DX9 gfx card anyway, so it's automatically disabled for those systems.
