    Does anyone know where I can find a copy of Windows XP 64-bit Edition (not Professional) that was made for Itanium systems? I've looked everywhere, but I still can't find it.

    do not know which of the above are the ones for the Itanium systems, you can read more on the Itanium systems at wikipedia, here is an excerpt:

    Windows XP 64-Bit Edition
    "Windows XP 64-Bit Edition" redirects here. It is not to be confused with Windows XP Professional x64 Edition.

    Windows XP 64-Bit Edition was designed to run on Intel Itanium family of microprocessors in their native IA-64 mode.

    Two versions of Windows XP 64-Bit Edition were released:


    • Windows XP 64-Bit Edition for Itanium systems, Version 2002 – Based on Windows XP codebase, was released simultaneously alongside the 32-Bit version of Windows XP on October 25, 2001.[36]
    • Windows XP 64-Bit Edition, Version 2003 – Based on Windows Server 2003 codebase (which added support for the Itanium 2 processor), was released on March 28, 2003.[37]

    This edition was discontinued in January 2005, after Hewlett-Packard, the last distributor of Itanium-based workstations, stopped selling Itanium systems marketed as 'workstations'.[38] As of July 2005, Windows XP 64-Bit Edition is no longer supported, and no further security updates were made available.

    Windows XP 64-Bit Edition was not marketed as the Itanium version of Microsoft's other Windows XP editions, but, instead, as a separate edition made solely for the Itanium processor and its 64-bit instructions. It is mostly analogous to Windows XP Professional, but numerous older technologies, such as DAO, Jet database, NTVDM, and Windows on Windows, are no longer present, so support for MS-DOS and Win16 applications is absent. The original version also lacks most media applications, such as Windows Media Player, NetMeeting, Windows Movie Maker, and integrated CD burning, although WMP and NetMeeting were added in the 2003 version.

    Similar to the ability of previous alternate architecture ports of Windows (Windows NT 4.0 for PowerPC, MIPS R4x00, and Alpha) to run 16-bit x86 code via Windows on Windows, Windows XP 64-Bit Edition can run standard x86 32-bit applications through its WOW64 (Windows-on-Windows 64-bit) emulation layer. While the original Itanium processor contains an on-chip IA-32 decoder, it was deemed far too slow for serious use (running at about 400 MHz), so Microsoft and Intel wrote a software 32 to 64-bit translator dubbed the IA-32 Execution Layer. It allows real time translation of x86 32-bit instructions into IA-64 instructions, allowing 32-bit applications to run (albeit significantly more slowly than native code).
