Hi everybody,
I recently had the same issue, and now that Boot Camp 4 is out, it is very difficult to locate drivers from before Boot Camp 3. I managed to find Apple trackpad drivers from Boot Camp 2.1, and using these drivers instead of the latest ones have so far solved the aapltp.sys bsod problem.
You'll need to uninstall the old trackpad drivers in device manager under Human Interface Devices. However, upon doing so, you will temporarily lose the use of your trackpad entirely. Use the keyboard to alt+tab and navigate to the trackpad install file (one for 32 bit Windows and one for 64 bit Windows). Using a combination of tabbing, arrow keys, and enter - I installed the old trackpad drivers, rebooted, and no more blue screen!
The only drawbacks I've discovered are that you lose the ability to tap to click, and the pointer and scrolling sensitivity are slightly different (but you can adjust these in the control panel under Mouse).
Here is a link to the old trackpad drivers: https://anonfiles.com/file/82cf29ce5...20adb515b8d08d
Hope that helps somebody!
