I can't install this build. My laptop turn off after "just a moment" is stuck and connect with defaultuser0 that I don't know its password.
I had to delete my history in Edge to get the new tab page to work again with showing the most visited sites and the newsfeed.
Updating my Insider PC to 14946 without perform a clean install. I hope that the "Just a moment" bug will not appear
I have never experienced such issue as that since I have been upgrading my Insider Previews. When people report it I kind of ponder on the reason they are getting it. Most time, as in the case with Windows 10, is caused by incompatible drivers, applications, etc.
Microsoft already knows about this bug. I didn't have the Just a moment bug but I get several ones related to Intel drivers. I hope that this will get fixed soon.
