Registration of an application in a per-user registration model includes the creation and storage of duplicate registration data for multiple user accounts present on a system. This duplication of registration data may be reduced by storing at least a portion of identical data in a per-machine location in the system memory where it is accessible to all user accounts. Instead of needing to separately re-compute and/or re-store duplicate registration data in multiple per-user locations in the memory, each user account may access and utilize the registration data stored in the per-machine location. Pre-computing and storing a portion of the application registration data in a per-machine location in the memory may also allow the system to defer the registration of the application.
