For some strange reason, all the icons on my desktop accessing websites became 'Microsoft Edge' when I switched from Chrome to Edge for one browsing session! I tried everything to get rid of it, but no luck! Also, when I want to make Mozilla Firefox my default browser, as soon as I click OK, an 'Edge' page comes up thus nullifying my preference! Apparently, Microsoft has a wired software app overriding one's choice? How can I disable it or get rid of it so I can get back my browser of choice?
windows 10 requires you to choose your default browser in the settings area of windows - (you can no longer just 'set this browser as default' within the browser application
go to settings/ system / default apps - and you can choose what you use under "web browser" heading
Note - edge is also the default pdf reader in windows 10 too..
