Get a unique computer ID in Python on windows and linux

by

There seems to be no direct “python” way of doing this. On modern PC hardware, there usually is an UUID stored in the BIOS – on Linux there is a command line utility dmidecode that can read this; example from my desktop:

System Information
        Manufacturer: Dell Inc.
        Product Name: OptiPlex 755                 
        Version: Not Specified
        Serial Number: 5Y8YF3J
        UUID: 44454C4C-5900-1038-8059-B5C04F46334A
        Wake-up Type: Power Switch
        SKU Number: Not Specified
        Family: Not Specified

The problem with MAC addresses is that usually you can easily change them programmatically (at least if you run the OS in a VM)

On Windows, you can use this C API
