TG Daily reports that several industry sources have confirmed that a very early version of Windows 7 already has been shipped to key partners as a Milestone 1 code drop.

The current M1 drop is available to Microsoft partners in English only and has shipped in x86 and x64 versions. An interesting feature that has been highlighted by Microsoft is the ability of the M1 software to handle a heterogeneous graphics system consisting of multiple graphics cards from different vendors. A new version of the Media center is already integrated in this software, but supports PC speakers only at this time.
