Well... It's much better than 8 and 8.1
installed it on a non-domain laptop that had windows 7 on it... 4MB download... reboots... upon next logon to desktop, pops up windows update... 2.6GB update.... reboot... voila Win 7 -> win 10!!!
If they get that update real solid... that will convince a lot of enterprises to upgrade due to easy migration! (Imagine upgrading everyone through your WSUS servers)
I also took the full ISO and installed it on a VM from scratch, and joined it to the domain... RSAT tools are also already available!!!
MS did their fuckin' homework this time!
