Update for Windows 10 and 11 blocks default browser redirect, but there’s a workaround
It seems that Microsoft has quietly backported the block, introduced a month ago in a Dev build of Windows 11, on tools like EdgeDeflector and browsers from being the true default browser in Windows 10, with the change being implemented in Windows 11 too. Starting from KB5008212, which was installed on all supported versions of Windows 10 yesterday with Patch Tuesday, it is no longer possible to select EdgeDeflector as the default MICROSOFT-EDGE protocol.
The change was also ported to the current version of Windows 11 with yesterday’s Patch Tuesday with the installation of KB5008215 rendering it impossible to choose anything but Microsoft’s Edge browser…
Fortunately, there’s a workaround against these anti-competitive … and desperate measures; first discovered by gHacks, the open source tool MSEdgeRedirect uses a completely different method. Instead of relying on the (now blocked) protocol handler, it “filters and passes the command line arguments of Microsoft Edge processes into your default browser “…
