first of all, you get some programs. resource editor (PE Explorer Resource Tuner, etc.) and the program that you can edit. cur files. I use a program called iconcraft.
i use trial PE Explorer: http://www.heaventools.com/download/pexsetup.exe
ok, now you must open nwindow.dll with PE Explorer. click on the Resources Viewer / Editor button or press Ctrl + D. Then select the entry pass, and now you can see the cursors. Right-click on one of them, and click Save Resource As ...
now, check the cursor with iconcraft or program in this style. if it is finished, you must open again nwindow.dll, and double-click on the selected cursor position. File Open Source or Ctrl + O, then OK. save the file, and now you can play and enjoy their own cursor.
Remember !! --- > to avoid errors, make a backup copy of data from each file that you are using. I think he will be useful to someone
