Abstract
Techniques are disclosed for enabling a system service executing in an isolated session to access system resources (such as a graphics processing unit) that it is isolated from. In an embodiment, the system service creates a 'worker' session that is not isolated, and a 'worker' process inside that worker session. Then, the system service is able to access the system resource that it is directly isolated from accessing by passing a request to the worker process to access the system resource on the system service's behalf. The worker process does so, and passes a result to the system service.
