mattwnz:semigeek: 10074 is out now on Fast Ring for those who haven't checked.
Does it give the option to go into the slow ring? The last update locked you into the fast ring, as the option to change it just got that rotating loading circle.
You get the option of going into the slow ring in settings. This build is very good as well. My start menu now launches all the time, something it wasn't doing on the previous build.
Edit - I spoke too soon. if I launch Paint and then close out and then go back to Start, Start won't launch for me. Can someone else try and see if they can launch Start after launching Paint?
