Unique Machune Id
how can I get my machine's unique id(eg: Processor/CPU/Hardisk/NIC)..
I am making an application for windows..
There is no Qt way of doing it I know of.
If you want to identify Windows installations you can use the Product ID (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProductId).
If you want to identify systems you can retrieve various hardware identifiers using WMI or the native Windows SDK.
