I did all of my scripting in Windows in JS. You had full access to COM objects, which means you could do a lot of stuff out of the box. One thing I hated was that it wasn't even fully ES3 conformant (it's jscript), and it seemed not to be maintained. I think they threw out cscript considerations when they built powershell. For me, a simple bash shell or even a jscript REPL would've been preferable. I think my favorite least-known thing about writing simple tools for Windows during my time as a sys admin was HTAs. You had full jscript COM access with a web page presentation that's packaged into something that you can run without opening a browser explicitly. It was awesome building full web applications that could do pretty much any administrative task on Windows.
