32 or 64 bit

[JACK]

I am running Windows XP. How do I know if I have 32 or 64
bit?

Thanks,

Jack

Hello all,

I will be posting this on several threads; however to tell if you have a
64-bit vs. a 32-bit computer, just run the System Information tool. (type
winmsd at in the Run box) If you have a 32-bit system, the "System Type"
listed should be something like"X86-based PC". If you have a 64-bit
system, you will see an entry stating something like "Itanium (TM) - based
PC". In addition, when looking at the processor(s) on the computer, a
32-bit system should start with x86 and a 64-bit will start with ia64.
(didn't check an AMD or other processors to see if they show different)

I also noticed that on the Windows 2003 Server I tested, that the winver
tool showed in the artwork that the OS was built for 64-bit hardware.
(don't remember the exact wording)

Best regards,

Most folks that have the 64bit version of XP are very aware of that fact
(it's expensive and runs only on very specific hardware). Chances are very
good to excellent that you are using the 32bit version of XP.
