The extended validation code signing certificate you need to avoid having your installer blocked by Windows SmartScreen is quite a bit more expensive.

IIRC it also doesn't stop the Smartscreen warning appearing.
This changed a couple years ago. EV certificates no longer get a free pass.

> EV certificates no longer bypass SmartScreen. Years ago, signing files with an Extended Validation (EV) code signing certificate would result in positive SmartScreen reputation by default, but this behavior no longer exists. EV certificates may matter for enterprise procurement, but they no longer impact SmartScreen behavior. Paying a premium for EV solely to avoid SmartScreen warnings is no longer justified.
