I looked over the second option and it's a pretty extensive patching process. The 2-3 hours they give for it is generous. Also it appears that they do do windows update manually, so it's still a fully up to date Windows 10 installation. I suspect you could get away with just running their script on a legit, fully updated, Windows 10 install, with presumably the UI modifications they want you to do (says the scripts need you to do that).
