Make window previews on the taskbar show quickier.

When you have the Aero theme enabled in Windows 7, you see thumbnail previews of the opened windows when hovering over the icons in the taskbar. However, there is a slight delay of 400 milliseconds for these thumbnails to load. If you notice the delay, you can decrease the delay time with the following Registry entry:

Hive: HKEY_CURRENT_USER

Key: Control Panel\Mouse

Value Name: MouseHoverTime

String Value: Default = 400 (milliseconds)
