Windows XP does not include any system cursors that are larger than 32×32. (If larger cursors were included, they would be stretched down to 32×32 when the standard APIs load the cursors.)
For high-DPI systems, Windows XP has adjusted the SM_CXCURSOR and SM_CYCURSOR values to be 64×64 pixels. This size adjustment is to prevent the mouse pointer from virtually disappearing because it is too small to be effectively used. Although the other aspects of the system scale with DPI, the mouse pointer does not scale. Microsoft does not try to enforce a DPI-independent size for the mouse pointer.
The system also provides the SetSystemCursor API function that you can use to change the system cursor for specific categories. You can use this function to set a cursor of any size. However, you must call the function programmatically, and you can only use it to set a cursor for a specific category. You cannot use it to make all cursors on the system the same size.
