Well, this time is a bit unusual. M$ releases ISO first on Slow ring, then push ESDs together with patches afterwards. M$ said that the ISO is mainly for people who cannot update thru WU. Anyway, no matter Fast or Slow, the ESDs (ISOs) will be the very same. So if you already have one, no need to have another.
I have seen that error in build 10130 when I tried to use the Guest account. Not much help I know but possibly permissions errors?
I couldn't do much on that laptop now, the error come back fast even after reboot! I downloaded thye latest ISO for 10130 from Microsoft already and will that to do a clean install on Laptop and see what will happen then!
I've just recreated the error, enabled the guest account and tried logging into it, BANG! no problem going back to my own account though. (build 10130 en-gb x64, clean install)
Build 10134 review: thurrott.com/windows/windows-10/4010/hands-on-with-windows-10-build-10134 When are we expecting the next fast ring build?
Tried 3 times to install .134 and .135 builds but couldn't go further the "Just a moment..." screen. Shame.
