Some times we need to manage IIS in a way that works better then the UI
For example you need the password for the app pool becuase you don't want to have to reset it 30 time
get all password for a user:
c:\Windows\System32\inetsrv>appcmd list apppool /processModel.userName:"$=WindowsUserIdenity" /config /xml > C:\Users\Administrator\Desktop\apppool.xml
Example: c:\Windows\System32\inetsrv\appcmd list apppool /processModel.userName:"$=IWPD_1(test)" /config /xml > C:\Users\Administrator\Desktop\apppool.xml
recycle all app pools for a user
c:\Windows\System32\inetsrv>appcmd list apppool /processModel.userName:"$=WindowsUserIdenity" /xml | %windir%\system32\inetsrv\appcmd.exe recycle apppool /in
