found it on discussions apple forum look for the LonerT's post Aug 25, 2015 7:24 PM in response to dioshy (quoting everything from there even though 2012 model is not your case but the solution still stands)"1. Please see BootCamp 6 update not available on MacBook Pro mid 2012 with Windows 10 for the two methods supported by Apple to get BC6 drivers.
You can manually download BC6 drivers from Apple CDN using Brigadier (https://github.com/timsutton/brigadier) by specifying your model number available from How to identify MacBook Pro models - Apple Support .
Please also see Use Windows 10 on your Mac with Boot Camp - Apple Support."
