Option 4 obviously doesn't work since it'll just enables itself like I said in my original post.
For now, I'll got with option 1 with the metered connection. I'll give it a day or 2 to see how it goes.
Option 6 is out of the question.
Option 2 is definitely a no.
Option 3 doesn't have a link to what you want me to download.
Option 5 sounds a bit tricky, mind me telling what is actually does by stopping all of those and is it safe?
