So the machine is running again... I wonder if the rumored November 2 TH2 release date still stands given this one is still labeled as a preview build.
It took 20 minutes total from the time I dl to the time it rebooted into 10576, everything seems to respond better.
This is the name you get: en_windows_10_pro_10576_x64_dvd.iso and this is the name you get for TH1: en_windows_10_pro_10240_x64_dvd.iso So, it is fine..
It's just a new update which brings us new stuff, no rtm, no final, win 10 will be continuosly developped and updated.
