UUIDGEN - Universally unique identifier

[zvivered]

I guess UUIDGEN creates a number which is unique on the local PC I'm working.
How can I be sure that this number is unique among all PCs in the world ?

This number is used for creating the file at the user level and for creating the device at the kernel level.

If a PC is installed with 2 drivers with the same number I guess it will cause problems.

Thanks.

UUID = UNIVERSALLY Unique Identifier

There are three algorithms to generate UUIDs:
1. Using the unique values of 802 MAC addresses to guarantee uniqueness.
2. Using pseudo-random number generators
3. Using cryptographic hashing and application-provided text strings.

Using one of the following algorithms will generate a unique identifier from all other UUIDs that have been or will be assigned.
