A few days later, SmartScreen will be aware of the digital signature used for the certified program and will no longer warn the users on download. Upload the XML result of a successfull application certification to. The best way to ensure that SmartScreen won't warn the users is to run the Windows App Certification Kit (WACK) which should be included in the Windows SDK download:Īfter running the tests, WACK explains how to proceed: To do so, they select Actions | More Options | Run Anyway from Download Manager. While a renewed certificate establishes reputation, users can still click through to run or save the download. However, known reputation on the renewed certificate is typically established more rapidly than on a new certificate. Please note that whenever you renew a certificate with known reputation, you will likely see some warns during initial downloads of files signed with the renewed certificate. More specifically, here is the reply I got from the SmartScreen® Filter's Application Reputation feature support team: Microsoft is claiming that if the old and new certificates have the same textual content, the reputation gets established faster.

You'll just waste a lot of time and energy.

Microsoft is no longer providing any means of transferring reputation from an existing certificate to a new one. We just went through the whole process of moving from an old Authenticode certificate to a new one (not an EV certificate, just a plain certificate that can be used in our automated build process).
