Microsoft stripped its calendar and photo gallery apps from Windows 7, but one extra it did bundle into the Windows 7 Preview is PowerShell, a souped-up command line and scripting GUI that frees you, finally, from the limits of DOS batch scripts. PowerShell is available as a free download for XP and Vista users, too.

If you're interested in learning PowerShell, then you can download the PowerShell documentation here: http://download.microsoft.com/download/4/7/1/47104ec6-410d-4492-890b-2a3... (ZIP file).
