The answer depends on the type of code signing certificate you have: • Extended Validation (EV) code signing certificates get an automatic SmartScreen reputation boost from Windows, so you should not get SmartScreen warnings after renewing an EV code signing certificate. • If you have a standard Organization Validation (OV) and Individual Validation (IV) code signing certificate, you will likely need to go through a period of rebuilding the renewed certificate's SmartScreen reputation before your code is widely trusted on Windows systems.
