    The nitty gritty ...

    Windows 10 Specifications System Requirements | Microsoft

    • Secure boot requires firmware that supports UEFI v2.3.1 Errata B and has the Microsoft Windows Certification Authority in the UEFI signature database.


    • Client Hyper-V requires a 64-bit system with second level address translation (SLAT) capabilities and additional 2 GB of RAM (Windows 10 Pro and Windows 10 Enterprise only).


    • To install a 64-bit OS on a 64-bit PC, your processor needs to support CMPXCHG16b, PrefetchW, and LAHF/SAHF.

    The last bullet in the requirements tells me that your hardware does not support Win10 x64.

    You can boot, but as soon as the install starts, nada, nuttin, Kaput. It would be better to fail gracefully, but.....

    Coreinfo, as requested by Kbird, should confirm that.

    Aside from the bit depth question though ...
    Win10 32-bit does see 4GB Ram.

    What does CPU-Z show ?

    It might be possible to upgrade your CPU, but since the machine is really old, you're probably better off getting newer technology - a new machine or rebuilding the old one with new Mobo, GPU, CPU, Wifi, PwrSupply, etc.
    I have no desire to be argumentative, but:

    EMT64 = PAE? I don't think so.

    https://en.wikipedia.org/wiki/Physic...ress_Extension

    I believe EMT64 = AMD64, more or less.

    The Intel archive has failed me in the past in providing information on those funky extra requirements (e. g., CMPXCHG16b) for running X64 under Win 10 (or Win 8.1). (No, I don't pretend to understand them.) Absence of mention may not equal absence.

    I don't disagree with your recommendations. I'm just not absolutely certain that Win 10 X64 can't be installed on this ancient hardware, pointless though it might be.

    C'mon - argument is what drives change

    Fair enough though ... I worded it poorly perhaps
    Not EMT64=PAE, rather as you say EMT64 = AMD64, both of which indicate PAE instruction support

    Better?

    I'm wondering if the question is: How do I get Windows to use the 4 GB of RAM - it only reports 3 GB usable.
    This is a question many people have.

    Physical Memory = 4GB RAM
    Graphics Memory = 0.5 to 1.0 GB RAM
    Usable Memory = 3.0 to 3.5 RAM

    PAE allows addressing above 4GB, but there's only 4 GB in the machine.

    Even with an x64 install and 6 GB, there is still 0.5 GB used by my graphics card.

    I agree that it might be possible to install x64 and also agree it might be pointless. You might be able to get around the pre-install checks but what happens when the next Feature update comes down?

    There are some HACKS that implement Server instead of Client deployment, but still, there's only 4 GB of PhysMem.

    We can argue (classical sense - debate/discuss ... I don't mind ) these things, but only hard data is definitive.

    I'll bow out until Christine posts Coreinfo that shows the instruction set supported by the CPU.
