I was able to get Windows 10 installed moments ago. The auto update seemed to be failing but you can down the iso manually via the new creation tool they put on their website moments after it turned midnight EST. Here is the link
http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10you can use that link to download the iso directly to your drive and as long as you are running a compatible OS (windows 7 or 8 ) it will autodetect and process the upgrade and give you a genuine copy of Windows 10 when done. Just be sure to download the iso for the same version of the OS you have installed now. For example if you have windows 8 Pro be sure to download the Windows 10 Pro as well or you will not end up with a genuine copy of Windows 10 at the end of the process.
Glad they made a way to perform the update manually I was itching to get windows 8.1 off my machine as fast as I possibly could!
