The subject invention relates to enabling device drivers that support additional functionality that can be enabled to an operating system. A hardware manufacture can claim support for additional functionality in their device drivers, and such functionality can be verified and tagged during driver signing. When a device driver passes a corresponding test, the driver is digitally signed and the signature can include attributes indicating support for that functionality (e.g., features and applications). The systems and methods employ a querying mechanism that can search a device driver package for attributes and expose such attributes. The search can expose both trusted attributes and untrusted device driver properties. Exposed trusted attributes can be selectively enabled to provide corresponding features and/or applications. This can facilitate enabling aspects of hardware when corresponding drivers support such functionality and mitigate enabling an unsupported feature and/or an application. Untrusted properties can be manually enabled, for example, for testing purposes. |
