Microsoft HLK EV code signing certificates

Microsoft HLK 要求 2015/10/31 之後必須有 EV code signing 憑證，舊的憑證檔可以用到2016/5/1。

EV Certs

• As of October 31, 2015, your Sysdev dashboard account must have at least one EV certificate associated with it to submit binaries for attestation signing or to submit binaries for HLK certification.
• You can sign with either your EV certificate or your existing standard certificates until May 1, 2016. After May 1, 2016, you need to use an EV certificate to sign the cab file that is submitted.

我申請最便宜的 DigiCert EV code signing Certificates，USD$ 224 / year。
網頁上申請後會接到一通確認電話，然後過幾天收到 USB key，到網頁上啟用就可以了。
