Figure 7   New SystemParametersInfo Values

SPI_GETMOUSESPEED
SPI_SETMOUSESPEED 		The same value as you'd set via the Mouse applet in the Control Panel.
SPI_GETSCREENSAVERRUNNING Is a screen saver currently running?
SPI_GETACTIVEWINDOWTRACKING
SPI_SETACTIVEWINDOWTRACKING		 Makes the active window "track" the mouse. Whatever window the mouse is over becomes the active window.
SPI_GETMENUANIMATION
SPI_SETMENUANIMATION		 If menu animation is enabled, menus will slide open. If disabled, menus pop up fully formed (just as in previous versions).
SPI_GETCOMBOBOXANIMATION
SPI_SETCOMBOBOXANIMATION		 If enabled, combo boxes slide open instead of pop open.
SPI_GETLISTBOXSMOOTHSCROLLING
SPI_SETLISTBOXSMOOTHSCROLLING		 If enabled, list boxes use the smooth-scrolling effect.
SPI_GETGRADIENTCAPTIONS
SPI_SETGRADIENTCAPTIONS		 If enabled, the background color of window title bars blends from the right to the left color. Use GetSysColor with the COLOR_GRADIENTACTIVECAPTION and COLOR_ACTIVECAPTION flags to specify the right and left colors for active windows. Use the COLOR_GRADIENTINACTIVECAPTION and COLOR_INACTIVECAPTION flags for inactive windows.
SPI_GETMENUUNDERLINES
SPI_SETMENUUNDERLINES		 If menu underlines are enabled, the menu shortcut underlines are always drawn. Otherwise, they are only drawn when the menu is activated through the keyboard.
SPI_GETACTIVEWNDTRKZORDER
SPI_SETACTIVEWNDTRKZORDER		 If active window z-order tracking is enabled, the active window will be brought to the top of the z-order.
SPI_GETHOTTRACKING
SPI_SETHOTTRACKING		 If hot tracking is enabled, the system hot tracks and displays tooltips for non-client area buttons and menu bar items.
SPI_GETFOREGROUNDLOCKTIMEOUT
SPI_SETFOREGROUNDLOCKTIMEOUT
SPI_GETACTIVEWNDTRKTIMEOUT
SPI_SETACTIVEWNDTRKTIMEOUT		 Active window tracking delay, in milliseconds. This happens regardless of the z-ordering mode (see SPI_SETACTIVEWNDTRKZORDER).
SPI_GETFOREGROUNDFLASHCOUNT
SPI_SETFOREGROUNDFLASHCOUNT		 This is the number of times SetForegroundWindow will flash the tray button when rejecting a request by another program to switch to the foreground.
