Starting with window application for retriving list of software and hardware installed on remote pc

I want to create an application that can give me a description of all the softwares and hardware installed on a computer that is connected through a Local Network.

In Hardware Description - I want something like the list shown in Device manager and in software d开发者_如何学Pythonescription i want a list of all the softwares installed in remote pc as shown in "add and remove programs".

How should i start for this. What i need to implement. I havent used any API before so plz be little descriptive so that i can implement them.

I'd start with WMI (Windows Management Instrumentation), I know you asked for the answer to be 'descriptive' but your question opens a pretty big topic and there probably isn't a quick 1,2,3 type answer for it.
