Q: How to fix Mac keyboard & mousepad on Windows Bootcamp

MacBook Pro 13-inch Late 2011 // Windows 8

Requirements: external mouse (using a keyboard alone might be possible, but I wouldn't recommend it)

                         & the latest Boot Camp Support Software for your model

It was a lot simpler than I thought. After hours of research I had fixed it when downloading the Bootcamp Support Software - Apple - Support - Downloads

However after rebooting the next day, I noticed it was as if I hadn't fixed anything at all.

After a few more attempts at fixing the issue: ending the bootcamp.exe task and restarting it, giving a go at the non-responsive Boot Camp Control Panel, and tons of reboots from repairing; I was finally able to find a solution.

First, I restarted and booted up in OSX. Went to the App Store and made sure everything was fully upgraded.

Then, I migrated back to Windows and opened up Device Manager.

Again I am warning you, do not continue if you don't have an external mouse.

The next step involves deleting the drivers that are, in a sense, corrupted.

Once you delete these drivers, you will not be able to use the internal keyboard or mouse on your Mac.

Open 'Human Interface Devices'

I uninstalled: Apple Keyboard             (the computer icon with the red x at the top)

                      Apple Multitouch

                      Apple Multitouch Mouse

After uninstalling the drivers that weren't working properly, I inserted my USB mouse and made my way to the Boot Camp folder. Then I opened the setup.exe and repaired.

The Boot Camp Support Software will reinstall the drivers you just uninstalled, and hopefully after a reboot you will be welcomed with fixed keys and a multitouch mousepad.

Best of luck!
