Use the Magic Trackpad with your Windows PC

Step 1: Download this patch (available for Windows 32-bit and 64-bit) from the Apple website but don’t run it yet. It’s an executable file but it won’t run on your Windows Desktop since it is intended only for users who are running Windows inside a Mac desktop using Boot Camp.

Step 2. Download a copy of 7-zip and extract the contents of the exe file that you’ve downloaded in the previous step.

Step 3. This will create a new file called “BootCampUpdate32.msp” – extract the contents of this file as well using 7-zip again.

Step 4. You’ll now have several sub-folders that are named like BootCamp3135*. One of these folders will have a file called “Binary.AppleWirelessTrackpad_Bin” – just add a .exe extension to this file and then double-click to run it.
