What are the key steps to develop a troubleshooting pack with a payload using TSPDesigner?

Using the official TSPDesigner tool (available in Windows 7 SDK v7.0 or v7.1), you set project properties, define a root cause, configure the troubleshooter and resolver to require elevation and disable interaction, then add your payload scripts (Troubleshooter Script and Resolver Script). After setting a digital signature (e.g., a test certificate), you build the pack, producing a .diagcab file containing the manifest, scripts, and signature. The payload runs with administrator privileges when the user executes the pack. Similar covert execution techniques are used in other attacks, such as exploiting clipboard in Windows.
