Remarks
Use a STICKYKEYS structure when you call the SystemParametersInfo function with the wAction parameter set to SPI_GETSTICKYKEYS or SPI_SETSTICKYKEYS. When using SPI_GETSTICKYKEYS, you must specify the cbSize member of the STICKYKEYS structure; the SystemParametersInfo function fills in the remaining members. Specify all structure members when using the SPI_SETSTICKYKEYS value.
