OK, Give this a shot - go to this page:
http://firstfooter.deviantart.com/art/DMZ-AA-56066304save the image that has all the cursors in it.
Next open with Gimp - select the standard arrow pointer using the rectangle select tool, select copy, then Paste as | New Image
Scale image to 32 x 32 px - save as 'normal.xcf' next export as '.png' file.
Next copy your .png files into your Windows | Users | Your name | Pictures folder.
Boot into Windows - change view settings to show hidden extenstions - rename .png file as .cur - now when you open mouse in Control Panel, select 'Pointers' tab, hghlight the one you want to change and browse to your Pictures folder with the .cur file in it.
