OP, have you considered that Microsoft simply knows better than you do? You say no to driver updates, but deep down, you really mean yes. Microsoft understands that.
I won't ask if you want a hug, I'll just give you one. There there.

Seriously though - what version of Win10 did you install to begin with? I'm (half-heartedly) wondering whether an older version had a bug that ignored the settings you applied. I'll probably have a Win10 build coming up in the next week or so, I can try setting it up and configuring it not to install drivers automatically and see what happens (I know for a fact that it will try to download the Intel graphics driver automatically because I usually rely on it to do that). If anyone has any other tips for what I could try to stop Win10 auto installing drivers, I'm probably willing to try them out.
