Use the "website" option at the top of each respective library and download from each location.

when i download cursor's, I can't change this on my computer.
How can I do this ??

I assume you downloaded the CursorXP program. If you haven't done so, you can find a link to it at the top of the CursorXP library webpage if you click CursorXP on the left hand side of this page. (You can do the same in order to get links to the shareware versions of WindowBlinds, DesktopX and so on, by going to the appropriate library page as KarmaGirl said).

Once you've installed CursorXP, you can download CursorXP skins and just double-click it to install. You can switch between your installed CursorXP themes by going to the Windows Control Panel and select the Mouse Applet. This will display the standard Windows mouse dialog box. You'll find a new tab on that dialog box called CursorXP. Now you can just select a theme from the dropdown list and press the Apply button
