We recently made some changes to Partner Center for Windows Hardware. As a result of these changes, all participants in the hardware program are required to reassociate their valid signing certificates used when making submissions to Partner Center for Windows Hardware. As a part of this process, you will need to reassociate both your Extended Validation (EV) codesign certificate, and your Authenticode codesigning certificate (if applicable). You need to take action now as any new submissions are blocked until this reassociation occurs. Additionally, you will be unable to publish any new content to Windows Update until your signing certificates have been updated.
