Default Full Android source code

Hey guys!! I'd like to know if there's a way to download the FULL android source code on MS Windows. I've done it in Linux, but I think it is not the full one, just android 4.4 (and still it is 20GB)...

There are some parts of older android version's tools which I'd like to download the source code. And, if possible, on MS Windows (if I have to do it on Linux it'll be fine, but I'd prefer to do it on Windows though...)

So, thank you very much in advance!!
