Question

I want to get unique unchangeable Machine id Like Processor serial number of the computer for distribute a software with out copying.

I tried with processor serial number and hard disk serial number that all are changing after formatting and reinstalling the windows.

Any idea how i can get an unchangeable serial number of a computer?

Answer 1

Maybe the easiest way is. Get the DeviceId Nuget package

And use it like

string deviceId = new DeviceIdBuilder()
.AddMachineName()
.AddMacAddress()
.AddProcessorId()
.AddMotherboardSerialNumber()
.ToString();

You can personalize the info used to generate the ID
