If you're using a Snapdragon-powered Windows 10 PC, then you're probably looking forward to Microsoft's Chromium-powered Edge browser. Unfortunately, it's not available in an ARM64 flavor just yet, so if you install it, you'll still get the emulated x86 version.
As seems to commonly be the case, a build leaked today, so those living on the edge (pun intended) can try it out. The signatures on the installation file do say that it's from Microsoft, although any leaked build is installed at your own risk. Apparently, there's no updater included either.
