Notepad? Link handling?

That's like my pencil having a CVE that's to do with how it loads the ink. That old saying about 'if Microsoft built a car' is more true now than it was then: https://www.snopes.com/fact-check/car-balk/

What does “unverified protocols” mean? Does Windows have an exe:// url scheme that fetches and runs executable binaries or something?

Is this a big deal? is it also not a problem with anything that renders clickable links? Browsers, email clients, whatever.

Is this not a problem with anything that offers a preview of markdown (or HTML, or anything with embedded links)?
