What is the best way to generate a unique hardware ID on Microsoft Windows with C++ that is not easily spoofable (with for example changing the MAC Address)?
407
You can use a PowerShell script (Get-WindowsAutopilotInfo. ps1) to get a device's hardware hash and serial number. The serial number is useful for quickly seeing which device the hardware hash belongs to.
Type the following command to name, brand, model, and serial number information and press Enter: wmic diskdrive get model,serialNumber,index,mediaType > C:\PATH\TO\TEXT.
A string that uniquely and consistently identifies a given specific machine or device. Typical Hardware IDs include computed fingerprints, MAC addresses, CPU serial numbers and hardware dongle identifiers. Software licenses are typically anchored to a specific Hardware ID.
Windows stores a unique Guid per machine in the registry at:
HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\MachineGuid
