HI Sebastian-5089,
Thanks for your waiting.
1.I've registered a cooperation in Canada a few months ago
Do you mean you have registered a business company in Canada? If the answer is yes, I think EV certificate is available.
2.Are EV certificates still the better option?
yes. If there is signed driver file included in your electron application, EV code signing certificate is required to establish a Windows Hardware Dev Center dashboard account.
"Signing your code is not required to earn a SmartScreen reputation, but EV-signed code’s extra level of trust lets developers skip this hurdle altogether:
An EV code signing certificate offers an immediate reputation with Microsoft SmartScreen, so your users will never have to click through a SmartScreen warning in Windows.
With an OV certificate, SmartScreen reputation must be built organically, as users download and install your files. SmartScreen warnings may occur until enough software proves sufficiently popular with Windows users for SmartScreen to view it as “well known.”
Unfortunately, Microsoft does not publish guidelines on what constitutes enough downloads to eliminate SmartScreen warnings. Microsoft has also indicated in the past that signing code is a “best practice” that you “can follow to help establish and maintain reputation for your applications.”
Do they still get the "instant" reputation these days?
From below document and I think it will be come true, we can contact SSL third party certificate company.
