First of all, you will need the hardware for this job. This includes an Apple Magic Mouse that will run you $69 from the Apple Store. And you will also need a Bluetooth 2.0 adapter in your computer. If you have notebook, then you probably have one built in, but if you’re on a desktop or don’t have one in your notebook, then you can easily get one for around $20.
Next, you need to setup your Bluetooth. Connect your adapter with your PC and install the hardware drivers. Pair up the Magic Mouse with your Windows from the Bluetooth Manager. Your mouse should now work as a standard two button mouse without any scrolling or multi-touch features.
To enable touch sensitive scrolling, you need to install a hacked Bluetooth driver for the Magic Mouse. By hacked, it means it was modified to run on non Apple hardware. The actual driver was released by Apple as aBluetooth Update for the iMac lineup to make the older models compatible with the new mouse.
The BootCamp version of the drivers were extracted from the Apple update by the people atUnEasySilence and slightly modified to run on non-Apple hardware. The drivers are available for both 32-bit (download) and 64-bit (download) version of Windows and work with everything from Windows XP up till Windows 7.
After installing the drivers, vertical scrolling should now work in Windows. Of course since this isn’t an official driver, you may run into some issues. Some applications still don’t accept the scroll input, while some even work with horizontal scrolling.
If the above drivers don’t work for your system, then you can try out Microsoft’s IntelliPoint SideWinder X8 drivers for your system. A lot of people have reported successful horizontal and vertical scrolling after using these drivers.
