1. Forcing people to use registry edit hacks is not an acceptable UI. There's no guarantee that those registry hacks won't stop working tomorrow. There needs to a real documented way to do it.

I have Windows 10 Pro. I used to disable Windows search doing web search with the Policy Editor (forcing me to do that was already boarderline unacceptable). Now that has stopped working, and even though I enable/disable many things in the Policy Editor, web search still happens. I will be switching to Linux.
