It takes literally a click to deactivate it though. One could argue about Bing Search being the default, but I didn’t run the user surveys to see, which is best for the average user.
Either I am stupid or you're being dishonest. There is no one click way to disable it. Only on pro versions of windows, with a group policy otherwise a couple of obscure registry keys no regular users know.
The best is none. I have no idea why anyone would want a web search there.
