Microsoft really making it difficult to switch default browser in win11

[nzoomed]

Yeah, that's what I thought. 
Like this here?
It's no longer visible on this machine of mine, it's a fresh install too, I will grab a screenshot later.

yep that's it, top right corner of the window.   Did you fresh install with latest version?  just thinking it may have turned up in a later version update

Turns out it's only on version 21H2, which is not even the latest version, despite windows telling me it was all up to date. Was a fresh install off the DVD.
Interestingly the set default button is now visible after a reboot and the 22H2 update is now showing up as available. 
However the likes of the media player defaults are still missing the button, but IIRC, the button was only ever available for the browser, either way it was more straightforward in windows 10.
