I don't know if you are still experincing this issue. Today I found a fix (workarround) For me the slow startup only happens when I sign in with a Microsoft Account. I converted my Windows account to a Local account and now the issue is resolved. I hope it also works for you. For help converting your online account to a local account see: hxxp://www.cnet.com/how-to/how-to-switch-your-windows-8-1-log-in-to-a-local-account/
