Show taskbar thumbnails as fast as possible?

[vsub]

Is there is a way to do this.
Before when I was on Windows XP,I was using a program called VisualTaskTips which had an option to display a preview of the window like here in Win7 and I had an option to choose how fast to see the preview once I point over the taskbar button(for the window).
The preview was set to be displayed instantly(it really was instantly)and when I move the mouse to another button in the taskbar,I had a preview of the next window instantly.

Currently on Win7 there is a delay before showing the window(I fix that with some guide from here...don't remember the link),delay before showing the next window when I move the mouse and kinda long delay before closing the preview window.

No change at all(added the key,set it to 10 and restart the pc)
It's acting the exact same way as before...fast showing(I change it from somewhere else)but not fast showing of the next window when I move the mouse and it's still waiting at least 1 second before closing the preview window

Edit:I also tried adding ThumbnailLivePreviewHoverTime(set to 0)but it was the same...no change
