What programming language is Windows XP and 7 written in?

Question:

What programming language is Windows XP and 7 written in?

Answer:

In fact, they are not written in one programming language, but in a mixture:

  • most of it is C / C ++ (with Visual Studio)
  • small part – assembler (masm, what else)
  • C # (this was not originally in XP, but for 7 there is already a lot)
  • hta (this is the way to build applications using html and scripts).

There is such a tale (I don't know how true it is, but very interesting) that they originally wanted to write Vista entirely in C # and .NET languages. Like it would be very cool (everything would be very stable and cool). But then they realized that it was simply impossible (at least – there is still no such iron that it would all take off). And they did it the old fashioned way – doped up XP.

If you are interested in how it works internally, then you can look at ReactOs – this is an attempt to make windows compatible operating system.
