Trigger started services are services in Windows 7 or Windows Server 2008 R2 that can register to be started or stopped when a trigger event occurs. This eliminates the need for services to start when the system starts, or for services to poll or actively wait for an event; a service can start when it is needed, instead of starting automatically whether or not there is work to do. Examples of predefined trigger events include arrival of a device of a specified device interface class or availability of a particular firewall port. A service can also register for a custom trigger event generated by an Event Tracing for Windows (ETW) provider.

In this screencast, Kate Gregory (@gregcons) provides an overview of trigger started services on Windows 7 via the Windows API Code Pack, a source code library that can be used to access some features of Windows 7 and Windows Vista from managed code.

Application Recovery and Restart (ARR) technologies enable developers to customize an application's behavior when Windows Error Reporting (WER) terminates the application due to an unrecoverable error. For example, it enables an application to perform data recovery and cleanup operations such as capturing application state and releasing resources before termination. It also allows developers to specify that WER should automatically restart an application that it has terminated.

In this screencast, Kate Gregory (@gregcons) provides an overview of ARR on Windows 7 via the Windows API Code Pack, a source code library that can be used to access some features of Windows 7 and Windows Vista from managed code. Kate also demonstrates just how easy it is to integrate ARR into your managed applications through a few lines of C#.
