In the EEA, much more is on the way:

Bing's web search from the Start menu and the Edge browser can be uninstalled Third parties can add to the Windows Widgets Board feeds Third parties, like Google or DuckDuckGo, can provide the built-in web search results that Bing once had exclusively Windows users who choose to sync their Microsoft accounts will have their pinned apps and preferences synced, seemingly keeping their EEA-enabled choices Windows will now "always use customers' configured app default settings for link and file types"

Good to see Microsoft just blatantly confirming that these are anti-competitive measures rather than any sort of technical limitation.
