There's probably a fancier answer to that, but you can just shell out to it: readall(`powershell -Command "Get-ChildItem -Path hkcu:"`)
This may end up being just a slower, different, equally hard-to-parse way of accomplishing what you were already doing via reg query, but powershell has a lot of scripting functionality that's orders of magnitude nicer than cmd. Unlike bash it's an object-oriented shell which is occasionally useful.
