Do they use Windows to write Windows? I don’t know, but if they did and suddenly there was no more Windows, what would they use to re-write Windows?

Your title makes good sense. But the second line in your question is hilarious… even though I get what you mean 😀 I had the same question long time back.
Same thing with machines. People use machines to build other machines today. What if there were all of a sudden no machines?… you start from scratch like pre-industrial revolution. Go one step back and use hand-tools to make machines and it starts all over. I guess people wrote Windows using compilers/tools in DOS and DOS using assembly and assemblers using direct machine codes and so on…
Whenever you get this doubt, think of it like this. You use hands to build a tool, use that tool to make a better tool, use that to make a better tool, etc… If at any point something happens to existing tools, you start with the best one you have available, even though it is a little outdated. Its really a simple concept, made to appear complex by the software development methodologies of today. Each (version of) operating system is only a tool to do something. You simply use the latest one available to build the next best one.

Visual Studio 2008 Team System was used by the team in Microsoft to develop Visual Studio 2010 Team System. If what I saw in a video is correct, they even used the previous build of VS to write the next build! Your confusion is perfectly understandable.. they call it dogfooding.
