Thank you PRoXimOn and all those who provided Input.
Proximon was right, For Situations where I have a PC in my workshop, that cannot Boot and has to be Reinstalled, this When I need to Find out if it is 64 bit compatible.
And Yes I know I could Use Barts CD to tell me what I want to know, But it would be better if I had a Simple little program that can be slipstream into my windows cd for this.
This would Cut waisted time.
I could Start a windows installation, either from a DVD Or a Flash Drive, and just where it asks you for the Location your in, I could Simply Use Shift F10, shell out to a command prompt, Run my x64 check program.
From there I can confidently decide weather to install x32 or x64 windows 7 ultimate.
