Hundreds of modules, scripts and Desired State Configuration resources have been registered with the PSGallery repository. Microsoft now recommends using the repository for module management. Using the Find-Module cmdlet, PowerShell makes a connection to the repository and gets a list of all available modules. Then, it runs a search on the returned results based on the criteria you mention.

You can also similarly find scripts that can perform repetitive tasks. To find scripts, use the Find-Script cmdlet. It works similar to the Find-Module cmdlet, except that it finds individual scripts rather than modules.
