This is my old implementation to get a Unique DeviceID for Windows Universal 8.1 but the type HardwareIdentification does not exist anymore.
private sta
//you can use this
//its working with me very fine on windows 10
//replace the word bios with any hardware name you want
//data also can be found with using windows application named (wbemtest)
using System.Management;
public static async Task ReturnHardWareID()
{
string s = "";
Task task = Task.Run(() =>
{
ManagementObjectSearcher bios = new ManagementObjectSearcher("SELECT * FROM Win32_BIOS");
ManagementObjectCollection bios_Collection = bios.Get();
foreach (ManagementObject obj in bios_Collection)
{
s = obj["SerialNumber"].ToString();
break; //break just to get the first found object data only
}
});
Task.WaitAll(task);
return await Task.FromResult(s);
}
