So I discovered something bizarre completely by accident. You can load Internet Explorer in Windows 11 without using Microsoft Edge.
I installed a serial monitor app, and the installer launched a HTML document. Not sure how this bypassed the Edge redirect, but it did.
You can browse the internet as normal too…
I’ve attempted a various number of things via the command prompt and none seem to allow me to just open the page in iexplore.exe.
Mind blown.
