The default Windows cursor scheme may seem boring after some time.
All three of these are available in all three sizes. The Windows Standard in the old non-Aero Windows XP styled scheme, the Windows Black is the inverted variation of Windows Standard, and the Windows Inverted is an inverted cursor scheme that adapts colour according to the background of the cursor. You have three additional scheme sets – Windows Standard, Windows Black, and Windows Inverted.
The default mouse cursor scheme in Windows is Aero White, which is available in three sizes – system scheme, large and extra large.
