how to disable horizontal scrolling with magic mouse in win7?

I use MagicMouse on iMac with Windows 7 running (installed through BootCamp). Got sick of annoying horizontal scrolling. The solution described above has helped me to disable it. Here is what I've done in steps:
1) go to http://www.autohotkey.com/ and download an app (a script editor).
2) Install and run the program - please note that it will not open as it runs in the background
3) Rightclick on the desktop -> choose "New" -> "AutoHotkey Script" (a new script file will be created on the desktop) -> name it as you wish (e.g. "Mouse_HScroll")
4) Rightclick on the file you've just created and choose "Edit Script" from the menu.
5) Add these three lines below existing text in the file:
WheelLeft::return
WheelRight::return
#MaxHotkeysPerInterval 5000
6) Save file
7) Run "Convert .ahk to .exe" program from the package installed earlier and browse the file you've just created, hit ">Convert<" -> .exe file should be created. Run this file -> the scrolling should be disabled now.
7) You may wish to move this file to Start/"Autorun" folder, so it would be launched automatically each time you reboot your Mac/PC.

Hope this helps! Good Luck
