tried using solutions posted here How to fast get Hardware-ID in C#? and here http://www.codeproject.com/Articles/17973/How-To-Get-Hardware-Information-CPU-ID-MainBoard-I but it seems wpf doesn't have ManagementObjectCollection. I've already add
using System.Management;
using System.Management.Instrumentation;
in my code, though. is there any way using wpf to get the cpu id and else?
