In this article, we will explore the usage of the Stop-EtwTraceSession cmdlet in PowerShell scripts. This cmdlet is specifically designed for the Windows environment and plays a crucial role in managing Event Tracing for Windows (ETW) sessions. Understanding how to effectively use Stop-EtwTraceSession is important for system administrators and developers who need to capture and analyze events in their Windows systems.

Examples:

Example 1: Stop an ETW Session

Stop-EtwTraceSession -Name "MyETWSession"

This example demonstrates how to stop an ETW session named "MyETWSession". By specifying the session name, the cmdlet will stop the session and halt the event tracing process.

Example 2: Stop Multiple ETW Sessions

Get-EtwTraceSession | Where-Object { $_.Name -like "MySession*" } | Stop-EtwTraceSession

In this example, we use the Get-EtwTraceSession cmdlet to retrieve all ETW sessions with names starting with "MySession". The output is then piped to the Stop-EtwTraceSession cmdlet to stop each of these sessions.

Example 3: Stop All Running ETW Sessions

Get-EtwTraceSession | Where-Object { $_.State -eq "Running" } | Stop-EtwTraceSession

This example shows how to stop all currently running ETW sessions. The Get-EtwTraceSession cmdlet retrieves all sessions with a state of "Running", and the Stop-EtwTraceSession cmdlet stops each of these sessions.
