I know we have "What is your security setup these days?" thread. The thing is that majority of posters still use x86 systems and it's not easy to pick posts that deal with x64 systems security. I recently moved to Windows 7 Ultimate x64 OS. I had to say goodbye to some of my favourite security progs like DefenseWall, SpyShelter and some other. We know about the limitations of 64-bit architecture due to that infamous KPP, a.k.a. PatchGuard. That's why I thought it would be a good thing to have a separate thread which would deal with x64 security specifics, so those of us who use it don't have to browse through numerous posts in the aforementioned thread. Post your x64 security setups, your suggestions and experiences, help us x64 noobs step into that challenging and unknown territory of 64-bit OS.
