Need windows drivers for Mac partition

the version of Windows 10 installer and Boot Camp Assistant do not play well together. In fact. Boot Camp Assistant has been totally useless. I had to Partition the drive using Disk Utility and now that Windows is installed and up and running Boot Camp Assistant wants to delete it before it will do a thing.

Windows does not recognize the wireless hardware, except to tell me I need a driver for it. Do I need to start over from scratch or is there another way to get support files for windows on a Mac partition?
