Change Registry Value in real time

I'm developing an application that requires changing the mouse pointer system-wide while the application runs (without rebooting or exiting the program). I am able to change the icon by changing the value under the Registry- HKEY_CURRENT_USER\Control Panel\Cursors\ using SaveSetting. However, the icon doesn't change unless I manually go into Control Panel, Mouse, Pointers. The changed icon shows up under Pointers, but does not take effect until I click OK. Is there a way I can force the registry to refresh/update the cursor real time ?


Thanks to anyone who has an answer !

Maybe this helps you.

Thanks ! I will give that a shot.
