Problem is with the 20.04 edition of Windows, there's no user friendly way to do turn that feature off.
Putting all of the privacy settings to the most restrictive values doesn't disable it, nor does turning off internet search in search in the policy editor. You have to dig around and create manually named registry keys. IMO that's unreasonable behavior.
But that makes you think there's likely dozens if not 100+ other things like that. I hope Windows tool makers don't stop uncovering these things.
I wonder if anyone will call out MS for having an option in the policy editor to disable internet search when using Windows search, while it doesn't actually disable it. What would the legal action be there? Maybe a GDPR violation since now the personal things I type into my computer are sent to Bing without my consent.
