One of the more interesting aspects of when Microsoft was working on Windows 7 was the fact that there were very few leaks of the new operating system but that hasn’t held true for Windows 8.  we have already seen copies of all the major builds hitting the web.

According to Tom Warren at Winrumors this is about to change. Well, for Intel workers at least.   Microsoft has apparently changed how the third milestone is locked down.

These are the reported changes:

“IntelDistrib would like to announce the immediate availability of Windows 8 x86 Client Build 8039 for testing at Intel.

NOTE:
There are two changes to the EEAP builds starting with this EEAP that you should be aware of:

• All OS installations using these builds will now require the unique key for the Windows Developer Preview. Installation with previous generic keys will no longer be supported. PRODKEY.TXT files containing generic keys will no longer be included in the build packages. You will have to get the New Product Key provided on the product site. This is a special key as part of the partnership Intel has with Microsoft.
• The name of the EEAP builds in this package contain “FBL_EEAP” instead of “WINMAIN”. This change is a name change only, and will not affect your ability to download or use these builds in your testing.”

Additionally it seems that Microsoft may have also really locked down some of the DLLs that are a part of Windows that have to do with the new user interface and other new features. This was done because in the past dedicated hackers would target them in order to turn on those new features.

Winrumors also has a list of some of the new stuff apparently found in Milestone 3 build.
