The cursor I am seeing is a regular mouse pointer, it's the STARTUP mouse icon, the one that no matter what mouse pointer you select, windows will still use this on the "Welcome" screen, until windows is loaded, then it changes to whatever cursor you have selected. It use to show for several seconds, but after modifying the registry and other setting, it just flashes now, but it's still annoying.
My welcome screen is blacked out and I have made a custom black cursor, but as I said, Windows still uses that default cursor. It only appears for a fraction of a second, but my brother noticed it the first time he saw my cabinet, so I would like to get rid of it.
