Disable Windows Update download?

Is there a way to totally disable Windows Update like the last versions?

I maxed my data because I think Windows Update doesn't recognize my phone's mobile hotspot as a "metered connection". Either that or it simply doesn't work for all metered connections.

I checked the Advanced Options but all I found was...

"You'll be asked to schedule a restart to finish installing updates. Updates won't download over a metered connection (where charges may apply)."

But this doesn't indicate that it won't "predownload" the updates.

Is there a way to toally turn this off. Cuz pretty much, this autodownload cost me like $40 and I didn't even notice it was happening while I was using my computer with my phone hotspot!

You could disable the Windows Update service. Of course I don't know what other functionality might be effected.
