![]() It does strong validation and produces correct results. But for my purposes this function is all I need. PS: The subprocess call could probably be replaced with ctypes directly calling Windows kernel/DLLs. Uses Windows API to get the computer's permanent UUID, then processes the string to ensure it's a valid UUID, and lastly returns a Python object ( ) which gives you convenient ways to use the data (such as 128-bit integer, hex string, etc). # Ensure we have exactly 32 characters (16 bytes). The following table lists the currently-defined versions for variant 2 UUID also known as RFC 4122/DCE 1. The new UUID can reasonably be considered unique among all UUIDs created on the local system, and among UUIDs created on other systems in. The uuidgen program creates (and prints) a new universally unique identifier (UUID) using the libuuid (3) library. ![]() The version field bits are the most significant 4 bits of octet 6 of UUIDs. On Linux, the util-linux / util-linux-ng package offers a command to generate UUIDs: uuidgen. # and useless dashes etc, by only keeping hex (0-9 A-F) chars. The type of UUID is determine by the version field bits. ![]() # Remove the surrounding whitespace (newlines, space, etc) The UUIDs generated by this site are provided AS IS without warranty of any kind, not even the warranty that the generated UUIDs are actually unique. The term GUID is generally used by developers working with Microsoft technologies, while UUID is used everywhere else. It is a 128-bit integer number used to identify resources. The Version 4 UUIDs produced by this site were generated using a secure random number generator. What is a GUID GUID (aka UUID) is an acronym for 'Globally Unique Identifier' (or 'Universally Unique Identifier'). # Attempt to extract the UUID from the command's result. A Version 4 UUID is a universally unique identifier that is generated using random numbers. Txt = subprocess.check_output("wmic csproduct get uuid").decode() A Version 4 UUID is a universally unique identifier that is generated using random numbers. # Ask Windows for the device's permanent UUID. ![]() from typing import OptionalÄef get_windows_uuid() -> Optional: If you want a permanent UUID that identifies a machine uniquely on Windows, you can use this trick: (Copied from my answer at ). ![]()
