Hi,
Can anyone lead me to a list of all 64-bit compatible processors for the 64-bit Vista? Or otherwise lead me to find a way on my own PC to check if mine is.

It says on my Everest that my CPU Instruction set: x86, x86-64. Since that 64 is there, does that mean I can run it? Other than that, besides the compatible CPU, is there anything else specific needed to run Vista 64-bit? Thanks guys.

Open your Device Manager.
Double click on Processors.
This will tell you what processors you have in your computer.

I have an Intel Core 2 Duo T5550 1.83 GHz. Does that help?
