Both environments support a few basic internal commands and a primitive scripting language ( batch files), which can be used to automate various tasks. The Windows NT and Windows CE families, however, came with a new cmd.exe that bore strong similarities to COMMAND.COM. (MS-DOS 5 came with a complementary DOS Shell.) The Windows 9x family came bundled with COMMAND.COM, the command-line environment of MS-DOS. MS-DOS and Xenix relied almost exclusively on CLI. The command-line interpreter (CLI) has been an inseparable part of most Microsoft operating systems. 5 Comparison of cmdlets with similar commands.Alternatively, help from the web can be acquired on a case-by-case basis via the -online switch to Get-Help. Updated local help contents can be retrieved from the Internet via the Update-Help cmdlet. PowerShell includes its own extensive, console-based help (similar to man pages in Unix shells) accessible via the Get-Help cmdlet. Other Microsoft applications including Microsoft SQL Server 2008 also expose their management interface via PowerShell cmdlets. This capability has been used by Microsoft Exchange Server 2007 to expose its management functionality as PowerShell cmdlets and providers and implement the graphical management tools as PowerShell hosts which invoke the necessary cmdlets. These applications can then use PowerShell functionality to implement certain operations, including those exposed via the graphical interface. PowerShell also provides a hosting API with which the PowerShell runtime can be embedded inside other applications. NET Remoting, WS-Management, CIM, and SSH enables administrators to perform administrative tasks on both local and remote Windows systems. Cmdlets may be used by scripts, which may in turn be packaged into modules.

Third-party developers can add cmdlets and providers to PowerShell.

These work by accessing data in different data stores, like the file system or Windows Registry, which are made available to PowerShell via providers.

NET classes implementing a particular operation. In PowerShell, administrative tasks are generally performed via cmdlets (pronounced command-lets), which are specialized. Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform on 18 August 2016 with the introduction of PowerShell Core. PowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language.
