What's the point in having the Start thumbnail? And if you want to have it hidden, they why the hell did you remove it in the first place? (You means Microsoft! )
From the PCBETA thread (translated): "Make it clear that here there is no download address, the landlord will not be available for download address, as they relate to confidentiality agreements, disclosure can range from being fired, the weight will be charged." Wow, a Chinese site named pcbeta too scared to leak an untrackable build. A lot of screenshot taking, NDA breaking, but nonleaking people out there. I would hate to think how boring what is now the golden age of OS testing would have been if these people were on the scene during the whistler, longhorn and win7 days.
Its my position that none of them are trackable. I think it was Rafael from WithinWindows that showed the added code to build string on Win8's watermark was not a tracking number. Even if it is it would be easy to get around by removing the watermark in sysprep and re-imaging the install before leaking. Either way, this build doesn't have a build string much less a so called "tracking" number.
