Resetting identity on web application pool from the command line

Ever wondered how to work with web application pools in IIS6 or IIS7 from the command line? See example below - it will (re)assign specific windows account for selected web application pool

SET SERVUSER=%COMPUTERNAME%\MyUser
SET SRVUSERPWD=PasswordHere
SET APPPOOLNAME=MyWebPool

echo will work for IIS6
CSCRIPT %SYSTEMDRIVE%\Inetpub\AdminScripts\ADSUTIL.VBS SET w3svc/AppPools/%APPPOOLNAME%/WamUserName "%SERVUSER%"
CSCRIPT %SYSTEMDRIVE%\Inetpub\AdminScripts\ADSUTIL.VBS SET w3svc/AppPools/%APPPOOLNAME%/WamUserPass "%SRVUSERPWD%"

echo will work for IIS7
%windir%\system32\inetsrv\appcmd set config /section:applicationPools /[name='%APPPOOLNAME%'].processModel.identityType:SpecificUser /[name='%APPPOOLNAME%'].processModel.userName:%SERVUSER% /[name='%APPPOOLNAME%'].processModel.password:%SRVUSERPWD%
