What is a Windows scripting language that: does not rely on .NET and offers the most OOP support and has simplest deployment?

It doesn't necessarily need to be a scripting language; It can be in the form of a compiled executable, however it needs to be self contained--only ONE file, no DLL's and it cannot be declared to "include" other files. I cannot rely on the user having any .NET installed and it needs to be able to run on Windows 7 64 bit.

By "most OOP support", I basically mean anything that has better OOP support than VBScript.

A little context: Everything I have done thus far is in VBScript and writes a bunch of data into an .html file, which in the end is to be viewed by Internet Explorer. It also zips up a bunch of directories and files. It heavily relies on accessing the registry, file-system, and WMI (I can probably do without accessing WMI though, as long as I have good registry access).

I can bring myself to code in any language so long as it meets me ridonkulous requirements stated above.

I look forward to some good answers from those more experienced than I.
