Finding trackpad driver for Bootcamp/Windows 10

I have recently installed windows 10 on Bootcamp. My apple trackpad was working fine, until I tried to install un-listed software that would provide additional settings for the trackpad. I ran the installation, and it didn't work. After rebooting, I noticed that windows was running in test mode, so I found a way to reset that, and then rebooted. After this I got stuck without a trackpad.

The software installation had done something to the device driver, and it was not working. I deleted the trackpad driver and I am now looking to reinstall it with original settings. Where can I obtain driver for the reinstall? I am on a MacBook Pro - late '16, windows 10 pro.
