Bootcamp 6.1.13 Download

Bootcamp on windows recently wanted me to update (to 6.1.15?) so I did. Now it's using the Windows touchpad settings which are horrible and I want to go back to Bootcamp 6.1.13 and use the mac drivers.

Will uninstalling the current version and reinstalling 6.1.13 work?

Does anyone have a link to where I can download 6.1.13? I've been looking but haven't found it.

Thanks!
