A method of generating a unique identifier without requiring platform-specific software, a computer readable medium embodying instructions for implementing the method, and a system therefor are described. In response to an event occurrence on a computer system, execution of the method retrieves an event timestamp from an intermediate operating environment on the computer system. Further execution of the method retrieves a system name and a hash value from the intermediate operating environment on the computer system. The combination of the system name, event timestamp, and hash value creates a unique identifier uniquely identifying the intermediate operating environment on the computer system without requiring platform-specific software.
