Cmdletlisäosat

Cmdletlisäosat, also known as PowerShell snap-ins, are components that extend the functionality of the PowerShell scripting environment. They are essentially assemblies that contain cmdlets, providers, and other PowerShell components. Snap-ins are used to add new cmdlets, providers, and formats to the PowerShell environment, allowing users to manage and automate tasks in various areas such as Active Directory, Exchange, and SharePoint.

Snap-ins are typically installed as part of a software package or can be downloaded separately. Once installed, they can be added to the PowerShell session using the Add-PSSnapin cmdlet. For example, to add the Active Directory snap-in, a user would run the command Add-PSSnapin -Name "Microsoft.ActiveDirectory.Management".

It's important to note that snap-ins are being phased out in favor of modules, which are a newer and more flexible way to extend PowerShell. Modules can contain cmdlets, functions, workflows, and other PowerShell components, and can be loaded into a PowerShell session using the Import-Module cmdlet. While snap-ins are still supported in PowerShell 5.1, they are not available in PowerShell Core, which is the cross-platform version of PowerShell.

In summary, cmdletlisäosat, or PowerShell snap-ins, are a way to extend the functionality of the PowerShell environment by adding new cmdlets, providers, and formats. They are being replaced by modules, which offer more flexibility and are available in both Windows PowerShell and PowerShell Core.
