Waits until a particular event is raised before continuing to run. The Wait-Event cmdlet suspends execution of a script or function until a particular event is raised. Execution resumes when the event is detected. To cancel the wait, press <kbd>CTRL</kbd>+<kbd>C</kbd>. This feature provides an alternative to polling for an event. It also allows you to determine the response to an event in two different ways: - using the Action parameter of the event subscription - waiting for an event to return and then respond with an action
