32 or 64 bit

[Greg]

I am trying to cleanup the worm from my wife's computer.
She is running XP. How do I tell if it is 32 bit or 64
bit.


Thanks for the help.

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)
