    In certain situations, there's no reason or benefit to run 64 bit, or if the user has some incompatible, crucial software. I still put 32 bit versions on older systems that have less than 4 GB of memory and I know won't ever be upgraded.

    Why is it a surprise ?

    I've installed 32 bit Windows 10 on an old laptop (9 + year old) even though it will run the 64 bit version. Why... its basically down to the lack of driver support, primarily Wi-Fi (Atheros) and the fact it only has 2Gb RAM.

    I have a Dell 1420 laptop bought at least 5 years ago. It came with Windows Vista running 32-bit but with a 64 bit processor.
    I have since upgraded it to Win 8 Pro > Win 8.1.1 > and now Win 10 Pro 32-bit.
    At one time while it was still running Vista, I tried to install a 64-bit Vmware player to try out Win 8 Preview and Vmware won't install until I switched to a 32-bit version.
    I have been wondering about that for quite a while.
    32-bit os will only run 32-bit software. 64-bit os will run both 32 and 64 bit programs.

    The very similar user interface tends to hide the fact that internally 32 and 64 bit operating systems are VERY different. A 64 bit OS can run most 32 bit software but this is not an inherent capability but something that must be designed in. And it isn't simple. The native environment in which 64 bit applications run is quite alien to a 32 bit application. A 32 bit process runs in a carefully prepared artificial environment where everything is as expected. The OS lies to the process about many things because it quite literally could not handle the truth.

    When running a 32 bit OS a 64 bit processor switches into 32 bit mode because only in this mode would it behave as expected and only in this mode could it run 16 bit applications. The CPU is identified to applications as a 32 bit CPU because for practical purposes that is what it is. Only when running a 64 bit OS does the CPU reveal it's true nature.

    That is because it is a 64 bit CPU.
