RegFolder

This package provides a Shell Namespace Extension which allows you to browse and edit the Windows Registry from the My Computer folder. It creates a virtual folder in the My Computer folder and populates the Windows Registry branch inside it.
Shell Extensions (NSE) are plugins for Windows Explorer and they enable you to extend Explorer with virtual folders, such as the current Windows implementation of the Recycle Bin and Zip compressed folders (where you can navigate into a zip file and browse its contents).
Shell Extensions can extend Explorer in several ways, such as adding new menuitems, Property Sheet pages or assign preview handlers to a file extension. In addition, you can create new virtual folders that act like regular file-system folders, but display items (files) that reside on a completely different media.
In the Registry folder you can browse and edit values of the registry under the HKEY_CURRENT_USER branch (or HKEY_LOCAL_MACHINE if you launch Explorer under the Administrator account). And while you can also create new keys and values just like the RegEdit tool, you may not find it much easier to work with. Its a programming example, its purpose is to demonstrate how to create a virtual folder in Windows Explorer.
