I don't know if it will be released today or not. When it is I'm ready. I made a image of my drive yesterday.
It's only just gone 5.00am in Redmond where Microsoft are based.
They usually come out at 6pm in the uk (10am MS time)
Just under 5 hours if its coming today
By then, 1am here.
For those planning to do a fresh install, the new iso is up on the Windows Download site. Looks like the real deal, as the name is Win10_1511_English_x64.iso.
