No, Windows 11 presents two scary-looking popups for unsigned apps: - “Windows protected your PC” with some tiny blurb no-one seems to read and a single button labelled “Don’t run”. - If you do read the tiny blurb and spot the “More info” link, you can click it to get a summary about Windows Defender SmartScreen having saved the day by protecting you from this app by an “unknown publisher”, and then a second button becomes available that says, “Run anyway”. It’s pretty hostile and it effectively forces devs to throw 300-600usd/year at a cert provider plus spend time to configure signing via CI. There are also two levels of certificate, and the better one is only available if you’ve been in business for several years with an office address and public phone number (cert providers need to call you at your public number to validate your business ID). There are some ways around it (I think games distributed via Steam’s installer still don’t need to be signed) but those aren’t an option for many.
