Just wanted to quickly point out another use of the WIndows registry in Python: WindowsRegistryFinder [1]. This is an import "meta-path" finder that locates modules declared (not defined) in the registry. I'm not familiar with the Windows registry nor do I know if anyone is using this finder.

The "Modules" key (WindowsRegistryFinder in 3.3+ and previously PyWin_FindRegisteredModule) adds individual modules by subkey name, with the filepath in the default value (the filename can differ, but it can't use an arbitrary extension). The "PythonPath" and "Modules" keys both date back to Mark Hammond's Windows port in the mid 1990s.
