The question which is hard/impossible to answer is whether the people who downloaded the 32-bit build genuinely needed a 32-bit build or just did so out of habit or confusion. I know you can't believe everything you see with statistics, but as an example, the chart at the bottom of this page suggests new deployments of 32-bit Windows are negligible today: https://www.pcbenchmarks.net/os-marketshare.html there are existing deployments not accounted for there, but that may still suggest many of the 32-bit downloads of QEMU will end up being run on 64-bit hosts. If we were to apply our support platform rule of only targetting the latest 2 versions of the OS, this limits our targets to Win 10 and Win 11. Windows 11 dropped 32-bit IIUC, so we're talking about 32-bit installs of Windows 10 only - even in Win10 days all new physical hardware would have been 64-bit capable.
