The cmdlet is a Windows PowerShell instruction, pronounced as command-let. This is equivalent to the built-in instructions for DOS or other shell programs, the instruction name is formatted with a pair of verbs and nouns separated by a hyphen (-), and is usually singular; for example, the cmdlet instruction for the online query description is get-help, and the verb part of the name is roughly a get, set, add, Remove and so on (Letters are not case-sensitive).

It also includes a number of system management tools, simple and consistent syntax, to enhance management processing, common such as login database, WMI. Server software, such as Exchange Server 2007 and System Center Operations Manager 2007, will build Windows PowerShell.
