Just a few minutes ago, when I was just checking some things on TechNet to prepare to download Windows 8, I discovered that the download is there….
And it’s also available through MSDN, although the Subscriber Download page is still showing the Release Preview….
Just Enter Windows 8 in the search field…and press Go to start searching…..next you will see Windows 8 appearing in the list…
