Microsoft really making it difficult to switch default browser in win11

[Wainuitech]

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.

Maybe so, but Windows 10 is gone. Things change and move on what usually happens is some let the changes get to far ahead and instead of staying upto date and there only small changes, then when changing its a bigger learning curve.

Re the 21H2, if that's what's on the DVD then that's what will install. That's why its always better to go to MS and download the actual ISO version you are wanting, and while there will be some updates, there wont be many.

The biggest problems is Hardware drivers, some are installed fine others you need to get them. Usually there's only a couple, depends on the motherboard and other installed hardware.
