Demystify Win8 Developer Preview in advance for OEMs

        From Microsoft began to enter the Windows 8 milestone stage, Dell, Lenovo, Hewlett-Packard, Samsung, Nokia, ARM, Intel and other first-tier hardware manufacturers have received various versions of Windows 8. Microsoft provides a Windows 8 download address on a dedicated website for these vendors to download test and hardware compatibility as well as driver testing and Windows 8 functional testing.
Regardless of whether the Windows 8 developer preview version released by Microsoft on September 13th in the US is build 8102 or 8100, this version has already been obtained by major manufacturers.
However, the 810x version that OEMs get is completely different from the Windows Developer PrevIEw that will be publicly available for download.
As we all know, Windows 8 is by far the best operating system for Microsoft's confidentiality. The leaked information and leaked versions are the least in history. At the same time, in order to prevent functional leakage, the Windows 8 version that Microsoft sent to OEM partners is specially processed. For example, the name of the version CD image will be marked with EEAP. These EEAP versions are "bad" Windows 8 compiled versions, and new features are hidden. And the necessary system files are not, you can not extract more new features by cracking and modifying the registry.

The first Windows 8 795x versions that were leaked are not the EEAP version of the OEM, so you can see some new features through some Piller programs.
Microsoft's restrictions on OEMs. There is no way to do this. After all, there are several leaks in Microsoft's OEM partners. (For ordinary users, should they be grateful?). Of course, for core-level partners, such as Intel, Microsoft will be more tolerant.
From this feature version limitation, it restricts the confidential leakage of Microsoft's new version of the software.
After the Windows 8 Beta full-featured version is open for download, vendors are still able to get the latest internal versions on a regular basis, and there will be no more restrictions. At the same time, after the beta version, the possibility of leaking more versions is greater, because Microsoft's new features have been made public.
The situation is generally the same.
