Abstract

Methods, systems, and apparatus, including computer program products, for retaining the function of product activation schemes and other persistent state changes based on hardware identifiers, even when running in a virtual machine monitor. It can tie such schemes to a single identifier, e.g., a USB serial number, instead of the multiple hardware identifiers.
