When I was using windows 10 + linux mint for over the 2 years I never got a boot problem from windows update. You just need a separate EFI partition for linux boot loader.
My Partitions: Windows boot C: D: Windows recovery or some other crap Linux EFI for grub / (Root directory) Swap
I don't bother with separate /home because I never know how much I will fill up my disk
google on duckduckgo "Free Media Heck Yeah" There should be a site that gathers links to reputable sites with free content including anime
