Resolved 64- or 32-bit?

I haven't been able to determine for my Media Centre Edition of XP whether it's 32- or 64-bit. The Microsoft sites I went to didn't mention Media Centre Edition specifically. Is the answer obvious to any of you guys?

System:
Microsoft Windows XP
Media Centre Edition
Version 2002
Service Pack 3

Computer:
Intel(R)
Pentium(R) D CPU 3.40GHz

Thank you.

 

How to determine whether a computer is running a 32-bit version or 64-bit version of the Windows operating system

 

Thanks, Steve. It appears that I have a 32-bit system.

Thanks, Whiskeyman. I had read that article from Microsoft, but because it kept referring to Windows XP Professional I wasn't getting the same information by following their procedure with my Windows Media Centre Edition. So to be sure I decided to drop in here for an opinion.
