As the configuration store for the vast majority of applications, the registry plays a central role in system administration. It is also generally hard to manage.
While commandline tools (such as reg.exe) exist to help you work with the registry, their interfaces are usually inconsistent and confusing. While the Registry Editor graphical user interface is easy to use, it does not support scripted administration.
PowerShell tackles this problem by exposing the Windows Registry as a navigation provider—a data source that you navigate and manage in exactly the same way that you work with the filesystem.
