I see the same behavior with my MSIs. I've had better luck with my MSIXs. As much as I like being Store-free, I have a June 2025 release of an MSI-based app that still gets dinged by Edge and again by SmartScreen. A different MSIX-based app, with almost no users, gets dinged by Edge but not by SmartScreen. It's the same certificate. I can never be sure what other users are seeing, though.

tbh, I thought that I had built enough reputation on this particular MSI release, until testing it just now. Hate to see it :(

Yeah, same here. It's a black box. Nobody knows how it works or what you can do to make it hassle free.

MS went from "developers, developers, developers" to being a nightmare for everyone involved.

I actually liked Visual Studio 6 and the old MSDN. Now I only wish they were gone.
