Hardware ID Protection?

Hello,

Sorry if this is in the wrong forum! Before delving into the Win32 WMI classes, I wanted to make sure I didn't reinvent the wheel. Are there any libraries or API's available for Windows x86 & x64 which implement hardware ID protection? For example, I would like the library to get the motherboard, HDD volume ID, mac address, etc. I know some of these ID's can be altered easily, but I'm not looking to fool any advanced crackers.

I have already tried Hardware ID Extractor DLL and AzSDK. I would prefer to have the source code available to integrate directly into my application without external DLL's.
