Using ADLX in a system service application 

While ADLX cannot be used directly in a system service application, its functionality can be accessed in a system service application through a user mode process. A communication mechanism between the user mode process and the system service, such as shared memory, will provide the ADLX functionality to the system service.

To use ADLX in a system service,

  1. Create a system service application.

    Note: For more information on how to create a system service in C++, see ServiceCall C++ sample . For more information on how to create a system service in C, see ServiceCall C sample .

  2. In the system service, start a thread to complete the service work, such as ServiceWorkerThread.

  3. On the ServiceWorkerThread, get the token of the current process to create a user process using CreateProcessAsUserW.

    Note: For more information on how to create a user process into a service application in C++, see UserProcess C++ sample . For more information on how to create a user process into a service application in C, see UserProcess C sample .

  4. In user mode, process load ADLX and implement the desired functionality.

  5. In user mode, process implement a communication mechanism suitable for communicating with the system service – such as shared memory – and tie the ADLX data with the communication mechanism.

  6. Run the user mode process and the service application.
