There are also software problems: 32-bit Windows runs both 16-bit Windows and 16-bit, 32-bit DOS applications. But 64-bit Windows does not. Virtualization software like VMware and emulator software like DOSbox will probably be the necessary option if anyone still needs to run the above versions.
Although PC has a long history of support for compatibility and older versions, 16-bit, 32-bit and software software will become more and more difficult to use in the next few years. The driver does not support is also part of the cause. Another reason is that Intel also plans to stop supporting BIOS on firmware from 2020 onwards. This change will prevent you from booting the 16-bit OS (and most 32-bit OSs) on new hardware.
