CursorFX is a free program that allows users to customize their mouse cursors in ways far beyond what Windows is capable of doing on its own. CursorFX is the replacement for CursorXP which only ran on Windows XP systems. CursorFX runs on both Windows Vista and XP, and updates the Windows mouse cursor engine to support fluid animations, alpha blending, effects, real-time shadowing, user-action mouse states, mouse cursor resizing on the fly, color changing, trails, and much more.
A gallery for CursorFX cursor themes is available on WinCustomize.com to download hundreds of free mouse cursors, trails, effects, and more. CursorFX is a free program. A plus version is available for $19.95 that adds more features.
