I'm having the same problem. It takes me 30mins to start up my machine. It's a joke. I thought Microsoft lifted their game.
I should've bought a Mac book pro
That maybe a different issue, the startup issue we're experiencing doesn't appear to delay the startup process itself. Plus one of the latest firmware updates corrected the issue.
Maybe go through some of the common diagnostic processes to see what is causing your issue, IE disable the non system related startup processes etc.
