How to use in Windows?

Code not worked ...

#include <iostream>

#include "smbios/abstract_smbios_entry.h"
#include "smbios/smbios.h"
#include "smbios/smbios_entry_factory.h"

int main()
{
	smbios::SMBios bios;
	smbios::SMBiosVersion ver = bios.get_smbios_version();
	std::cout << "DMI version: " << ver.major_version << '.' << ver.minor_version << '\n';
	std::cout << "Table size: " << bios.get_table_size() << '\n';
	std::cout << bios.render_to_description();


	smbios::SMBiosEntryFactory smbios_factory;
	for (const smbios::DMIHeader& header : bios)
	{
		std::cout << "Header ID = " << header.get_type() << '\n';
		std::unique_ptr<smbios::AbstractSMBiosEntry> entry = smbios_factory.create(header, ver);
		if (entry)
		{
			std::cout << entry->render_to_description() << '\n';
		}
	}
}

Could you provide more details, like OS version? Did you try to debug? Which function return error? Does GetSystemFirmwareTable() from smbios_util/smbios/src/win_bios.cpp execute without problems?
Because currently the solution works perfectly under Windows in a desktop product (macOS and Linux are left for future though), so it could be a corner case.

smbios_entry64_ empty

render_to_description return nothing..

Check GetSystemFirmwareTable() return value. If it's a zero, call ::GetLastError() and check the code. Non-zero value is unlikely, because it's against function description and means memory buffer should be bigger, but I can't deny any possibility

GetSystemFirmwareTable not a zero

It's outside application scope then, and might be connected to last Windows Update. I'll check it out in nearest time.
You also can isolate the problem by calling GetSystemFirmwareTable() in your own console application and check the output
