shdw.exe is a light-weight (18 kB) utility that enables the drop shadow beneath the mouse cursor.
It is a common annoyance that many full-screen 3D applications disable the shadow and either 'forget'
to reenable it when they exit, or they are terminated abnormally. In either case, it is cumbersome
to have to open the mouse properties in the control panel in order to restore the shadow. However,
if you copy
shdw.exe to your
WINDOWS folder (typically
you just have to run
shdw in order to get the shadow back.
program shdw; uses Windows; begin SystemParametersInfo(SPI_SETCURSORSHADOW, 0, pointer(integer(true)), SPIF_UPDATEINIFILE or SPIF_SENDWININICHANGE); end.
