Blue Badge rev. 3 adds registry override bits, “Aero Peek” enabled

This day, last month, I released a small utility to patch system files in Windows 7 Build 6801, the build given out at this year’s Professional Developers Conference (PDC), to enable some features that Microsoft intentionally tried to hide from the public.

Chris Holmes and I were scratching our heads over Aero Peek, a feature that we knew worked in some builds, but wasn’t working on Blue Badge’d systems. I initially wrote it off as an unfinished quirk but I took another look…and noticed I totally missed a series of checks made in the registry. Each protected feature has a pair of enabling override bits that are checked for, one for those on the Microsoft domain and one for those that aren’t. I’m not sure as to the rationale behind that, but I suspect it was implemented this way to prevent Microsoft employees from leaking working override bits. Overkill in my opinion.
