RegistryWalker is a python script that makes use of Mark Hammond's Python for Windows Extensions. Windows users can easily download the python interpreter and the extensions from ActiveState, an organization that provides ActivePython. The python scripts for RegistryWalker can then be downloaded and run directly.
Of course, if that all sounds like a lot of work, there is an easier way! Using the magic of py2exe, the python scripts have been turned into a Windows executable program without the need for a separate Python installation. And with the awesome Nullsoft Sciptable Install System you are just a few mouse clicks away from installing RegistryWalker!
