Last month, Rafael eeleased a small utility called “Blue Badge”, 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.[…]Revision 3 of the tool no longer patches system files, no longer requires administrative permissions, and is no longer locked to any specific build. It inserts all the known protected feature GUIDs as of build 6956 into the current user’s branch of the registry. An anonymous reader confirmed this behavior is similar to the Microsoft-internal win7features.exe utility.
Yes, this will enable Aero Peek in 6801+.
