An improved system and method for a context-awareness platform that may be used to adapt an execution environment is provided. A framework with interfaces for setting, tracking, and getting context information about the execution environment of a computer system includes a context engine and a unified data store for aggregating context information at a platform level for access by executables running on the platform. The context engine may receive requests to perform context information operations from executables such as setting, tracking and getting context information in the data store. Upon receiving a notification of a change in context information, one or more executables may change the execution environment such as reconfiguring system settings. In this way, an executable may adapt its execution environment using context information.
