Hello,
This patch is for Windows 7 X64 RTM & Windows 7 SP1. It directly modifies ntoskrnl.exe & winload.exe to remove Microsoft's "PatchGuard" and requirement of driver signing.
This is accomplished by patching 6 bytes inside ntoskrnl.exe and four bytes inside of winload.exe ... it is file patch version of my existing
bootkit
I originally made this for myself... wanting to again be able to hook inside of ntoskrnl like with X86 Windows.
Hope that someone find this useful,
-Fyyre
