installing Windows on my Mac without sighted assistance

In my experience, with recent versions of Windows 10, you can get speech just by plugging in a set of headphones and launching Narrator right on the first setup screen. I recently reinstalled Windows 10 on a 2015 MacBook Pro, and I had speech the entire time. Note that when running Windows on a Mac, the Command Key acts as the Windows key, so to start Narrator, you would press Control-Command-Enter. Assuming there are no oddities specific to the 2017 MacBook Pro (I don't know why there would be any), you should be able to plug in your headphones and start Narrator as soon as the computer reboots into the Windows install.

on my mac, innisicially when I bootcamped the first time, had it split in half. that was in 2016. now, in 2020, I've got 60GB for Windows and the rest for macos. it really depends on what you use windows for how much you'll need. since you are a gamer, go high, but be carful, as you cannot do anything to the windows partition when it is create, thus, if you later decide you need mor e space on windows, or more space on macos, you have to remove the bootcamp partition and resetup everything. on may 30th, windows 10 2004/may 2020 update will be reliesed. for that update to run, you need to update your graphics drivers. I'm not sure if the 2017 MacbookPro has intel drivers, but most macs do. anyway to do that, downloaded the intel driver and support assistant, let it scan your hardware to tell you what it needs, and install what shows up. the only people who know of this update are Windows Insiders, and I am one on the fast ring. if you need any help with this update or anything else, email me at daniel.angus.macdonald@gmail.com.
