How to identify which w3wp.exe process belongs to which Application Pool in IIS

I received an e-mail today, where I was asked how to identify the IIS Application Pool and the corresponding w3wp.exe process. Actually it doesn’t need much and no extra tools are needed.

1. Open the Windows Task Manager by right clicking on the Taskbar and selecting Start Task Manager
2. In the Menu, open View / Select Columns…
3. Search the list for Command Line and enable the check box



4. Look for the w3wp.exe processes and expand the column for the command line

As you can see, the process is started with the name of the Application Pool in the IIS management console
