Tried the flight upgrade--it locked up and refused to finish and restored 14942...am downloading the esd now to go from iso.
Large Windows Store games like Gears of War 4, ReCore, Killer Instinct, Forza Horizon 3 and Rise of the Tomb Raider might fail to launch Keep that in mind...
Did not see it mentioned but with this build 14946 i just hit ctrl-alt-del for the first time and the background color is now a new red color. /edit all back to the plain ole blue after a reboot.
Success here, too. Soon as I moved to the iso, 14946 installed first time, no errors. (Mounted the ISO on a separate hard drive partition/separate physical drive and *upgraded* over 14942 without incident!) I experienced the second failure consecutively for the "flight" upgrade to 14942, and then to 14946, however. I note that I had a version of MalwareBytes installed but not active when I successfully installed 14942 yesterday on top of 14393.223 via ISO; but today I uninstalled MWB completely and found that the flight upgrade from 14942 to 14946 failed--but, again, that upgrading 14942 to 14946 sailed through via the ISO.
I tried installing 14942 and 14946 on a DELL Inspiron 5559 that came with Ubuntu, but after (Express settings) I get "Just a moment" for a very very long moment and the installation fails. However, Windows 10 RS1 14393 installs fine!! Windows 7 installs successfully but gets a blue screen with ACPI error after first reboot.. but uploading the proper drivers during installation fixes it.
On my 2nd system i get WU errors when i'm on the Fast ring, when i change it to Release Preview ring it doesn't show the error. EDIT: once every few times i try WU it works but no IP downloads are offered.
