• 07001 verifies any prestaged packages and downloads any that do not exist on the branch
  distribution point. While Technet does not explicitly state it,I
  believe this task is useful only on branch distribution points and is
  ignored on normal clients.

• 07002 causes the client to generate a new discovery data record (DDR). When the DDR is processed
  by the site server,Discovery Data Manager adds or updates resource
  information from the DDR in the site database.

• 07003 When a file is specified for collection,the Microsoft System Center Configuration Manager 2007
  software inventory agent searches for that file when it runs a
  software inventory scan on each client in the site. If the software
  inventory client agent finds a file that should be collected,the file
  is attached to the inventory file and sent to the site server. This
  action differs from software inventory in that it actually sends the
  file to the site server,so that it can be later viewed using Resource
  Explorer. This is a part of SCCM inventory functionality.

• 07004 collects information such as available disk space,processor type,and operating system about each
  computer. This is a part of SCCM inventory functionality.

• 07005 The client downloads its policy on a schedule. By default,this value is
  configured to every 60 minutes and is configured with the option
  Policy polling interval (minutes). However,there might be occasions
  when you want to initiate ad-hoc policy retrieval from the client—for
  example,in a troubleshooting scenario or when testing. This action
  initiates ad-hoc machine policy retrieval from the client outside
  its scheduled polling interval.

• 07006 collects software inventory data directly from files (such as .exe files) by inventorying the file
  header information. Configuration Manager 2007 can also inventory
  unknown files — files that do not have detailed information in their
  file headers. This provides a flexible,easy-to-maintain software
  inventory method. You can also have Configuration Manager 2007 collect
  copies of files that you specify. Software inventory and collected
  file information for a client can be viewed using Resource Explorer.
  This is a part of SCCM inventory functionality.

• 07007 collects the data that allows you to monitor and client software usage.

• 07008 initiates a scan for software updates compliance. Before client computers can scan
  for software update compliance,the software updates environment must
  be configured.

• 07009 Just after a software update installation completes,a scan is initiated to verify that the update
  is no longer required and to create a new state message that indicates
  the update has been installed. When the installation has finished but
  a restart is necessary,the state will indicate that the client
  computer is pending a restart.

• 070010 Similar to Machine Policy Retrieval & Evaluation Cycle,but this action initiates
  ad-hoc user policy retrieval from the client outside its scheduled
  polling interval.

• 070011 causes the Product Source Update Manager to complete a full update cycle. When you install an application using Windows Installer,those Windows Installer applications try to return to the path they were installed from when they need to install new components,repair the application,or update the application. This location is called the Windows Installer source location. Windows Installer Source Location Manager can automatically search Configuration Manager 2007 distribution points for the source files,even if the application was not originally installed from a distribution point.
