Using the Get-PSProvider Cmdlet

  • Artigo

Listing Your Installed Windows PowerShell Providers

Among other things, Windows PowerShell providers determine which data stores you can navigate through. For example, you can use the Get-ChildItem command to retrieve a list of all the files found in a folder; that’s because a provider exists for the file system. You can also use Get-ChildItem to retrieve a list of all the subkeys found in a registry key. Why? You got it: because a provider exists for the registry.

To determine the providers available for you, simply call the Get-PSProvider cmdlet without any parameters:

Get-PSProvider

What you’ll get back is - surprise, surprise - information about your Windows PowerShell providers:
