As example, You can quite use any scripting language for this purpose (Shell Script, Visual Basic Script, JScript, MS HTA... etc.). You can load files by means of wget or curl (yes, for Windows).
I think I'll use a simple .bat and curl to download the .7z. It should verify that K-Meleon is not running etc. but I was not sure of what files should I overwrite hence my question.
