Also be aware that even the new bootcamp 5 drivers can be updated. Download a new bootcamp 5 file from apple (available during the creation of the bootcamp partition) and you are set. Im pretty sure the driver is auto updating and not working correctly. Ill install the driver and it works fine till I shutdown the laptop and restart it.

If you are going to install windows 8, DO NOT use your old bootcamp drivers. anyways ever since I installed windows 8.1 fresh my touchpad wont work to a point. It seems there is a lack of awareness of the existence of bootcamp 5. This time when I ran the bootcamp 5 drivers, the machine did not crash. I deleted my windows partition, recreated it, downloaded bootcamp 5, and reinstalled windows 8 pro. I googled bootcamp version and discovered that there is a bootcamp 5. The first couple of times I installed win 8 on the 17 inch mbp, after updating the drivers with the bootcamp 4 drivers, the machine kept crashing and rebooting. I like windows and have installed win 8 enterprise (see volume licensing) as my main desktop o/s at home. I usually use the 2010 machine to experiment. A 17 inch 2010 macbook pro and a 15 inch 2011 macbook pro. If your touchpad isn’t working, it may be a result of a missing or out-of-date driver. If Windows doesnt find a new driver and reinstalling the driver doesn’t help, contact your PC’s manufacturer for help. without hacks or other work-arounds as is currently required now. Windows will attempt to reinstall the driver. I truly hope that Apple very quickly releases a new Boot Camp which is 100% compatible with Windows 8, to solve all of those issues for real. Here is one such thread which has most of the 'tricks' to get it 'mostly' working in Windows 8 compiled into a single discussion:

However, as found within these Apple message forums, there ARE some work-arounds to get it 'mostly' working, by using wacky methods such as downgrading your Windows login permissions to User-level instead of Admin-level to get them to PARTIALLY run, etc. I just got off the phone with AppleCare support, who confirmed that, as of today 11/1/12, the above-mentioned versions of Boot Camp are NOT 100% compatible with Windows 8, and furthermore that there is currently NO 'officially' supported Boot Camp for Windows 8, period. This is the Windows-side utility that lets you easily reboot back into OSX, set the track pad settings such as enable right-click, etc.

exe version 4.0 as reported in Help->About, or, version 4.0.2.0 as reported in File->Properties. Windows 7 = Boot Camp Task Bar Tray Icon =. This is the OSX-side utility that paritions the OSX disk, lets you download the Windows drivers set, etc. OSX Mountain Lion 10.8.2 = Boot Camp Assistant =. This thread is very confusing and misleading, because Boot Camp has two parts, or 'sides' if you will, and it reports different version numbers depending on if you're talking about when running OSX the 'Boot Camp Assistant', or, what it installs into Windows 7 known simply as 'Boot Camp'.
