W3Wp is attached to which application pool IIS 7.0

often we need to know worker process (w3wp.exe) is attached to which application pool in IIS . in IIS 7 we can check it by
the following
Start > Run > Cmd
• Go To Windows > System32 > Inetsrv• Run appcmd list wp
i.e
c:\windows\system32\inetserv\appcmd.exe list wp

this will do the work and if we want them to export them in text file we can use

c:\windows\system32\inetserv\appcmd.exe list wp > wp.txt
