Re: How to find the operating system bit (x86/x64/ia64)

Reading back, I realize there was one point that I may not have made explicit: the values represent an OS architecture, not necessarily a specific manufacturer. So if your system is running a non-Itanium Intel x64 chip - which uses the AMD64 architecture - the 64-bit Windows will return AMD64 for PROCESSOR_ARCHITECTURE. As another and very far-fetched example: suppose a mysterious Eastern European company comes up with a reverse-engineered Itanium-compatible design tomorrow and markets it as the SkopjeCPU. Since it looks and acts like an Itanium, the only versions of Windows that will install on systems with the SkopjeCPU will be builds compiled as IA64; and if you check PROCESSOR_ARCHITECTURE on a SkopjeCPU machine, it will come back as IA64.

Kiran,

It turns out that you already have the answer with the script Paul showed if you just check the value he points to rather than using the post-processing via MsgBox.

The PROCESSOR_ARCHITECTURE value contains a string describing how _Windows_ perceives the CPU. if it's AMD64 cpu, you get AMD64. If it's IA64 the value is IA64. If it's an x86 CPU, OR if you are running 32-bit Windows directly on an AMD64, you get back x86.

Since you can access the machine key of the registry remotely using WMI, this is a good test for determining the OS architecture on a network of machines as well.

Hi PaulM,

Thanks for your script.

However, I need further granularity in case a 64 bit operating system
is detected. I need to differentiate if it is as x64 or an ia64
operating system type.

Is that possible with some additions to your script?

Thanks,
kp
