UnregisterPSRepository

Unregister-PSRepository is a PowerShell cmdlet used to remove a previously registered PowerShell repository from the current user's session or the machine's configuration. PowerShell repositories are sources from which modules can be installed and updated. When a repository is registered, PowerShell can discover and download modules from it.

This cmdlet is used to manage the list of available repositories. If a repository is no longer needed, or if it is outdated or inaccessible, Unregister-PSRepository can be used to remove it. This helps keep the list of available repositories clean and relevant.

The basic syntax for Unregister-PSRepository is Unregister-PSRepository -Name <RepositoryName>. The -Name parameter specifies the name of the repository to be unregistered. You can also use the -Force parameter to unregister the repository without being prompted for confirmation. To see a list of currently registered repositories, you can use the Get-PSRepository cmdlet.

Unregistering a repository does not delete the repository itself from its source, nor does it uninstall any modules that were previously installed from that repository. It simply removes the reference to that repository from PowerShell's configuration. This means that modules installed from the unregistered repository will still be available for use, but they will no longer be able to be updated or discovered through that specific repository source.
