Rooted.
My feedback for areas I got stuck on (aside of my OVPN client not working and me thinking it was a flaky shell):
I got stuck on some injection right at the beginning. I sat down and wrote down what I thought was the query being executed, then wrote into that what I would do to bypass it. Copied and pasted and that worked.
Spin through Wikipedia’s page on new features to Windows 10. There are some really weird looking directories and files on the box. It should ring some bells when you see it in the Windows 10 feature listing.

At this point, start enumerating like you would do a new box.
Good luck!
