As might be expected because of the expectations and the lack of official information on Windows 8, a preview of what system runs on the web.
This is actually the 7850 build of Windows 8 Milestone 1, ie a version that does only the beginnings of Windows 8 and does not necessarily signal what we find in the end or not in this new system Operating under the successor to Windows 7 in 2012.
In addition, this build which weighs 2.45 GB is not very recent, having been compiled September 29, 2010, Microsoft developers now working on Windows 8 Milestone 3, a version which should be finalized in June.
The site publishes BetaArchive in all cases of screenshots of Windows 8 Build 7850 Milestone 1, which suggest an interface very similar to Windows 7. This is not surprising knowing that in general developers focus primarily on the functionality and heart of the operating system before tackling its "skin".
