Which operating system is used to write Microsoft Windows?

Question

Yes, I actually mean the operating system. I have read a language related question and its answers in archives. Computers that Microsoft uses have to have some kind of OS on them. I heard somewhere that they use Linux.

Answer 1

Ummmm, Microsoft Windows is an operating system itself.

Answer 2

They don't use Linux for sure.
Microsoft Windows is written using Visual C/C++ which runs only on Windows.
Microsoft Windows is used to write Microsoft Windows.

Answer 3

Microsoft Windows is written with C and C++, it took 15,000,000 lines of code to make Windows Vista. And there is no designer mode, all you do is coding and the testing. But they don't use and OS, if they did I would either say Windows NT or Unix, Well with vista they would use XP so that they can run Visual Studio, which is an application used to write C & C++.

Answer 4

The guy means which operating system does Microsoft use while writing the Windows code. I believe they use their own OS.

Answer 5

Microsoft Windows developers likely use a Microsoft Virtual Machine environment using both MS Assembler and C/C++ , including the Visual versions where they can.

Answer 6

Err, I think you mean what programming language is used to write Microsoft Windows!
XP is a Unix based system, using a mix of C++, and visual basic.

Answer 7

C and C++.

Most likely there is some assembly thrown in there at times to optimize speed in places.

Those are programming languages though. They most likely write it all on Windows XP SP2 boxes until their next OS is good enough, and then they write the new parts for it in itself.
