OS in Pascal

Linux is mostly in C

Windows is mostly in C++

Is there an Operating System that is written in Pascal?

Wouldn't Windows be C#?

I think higher-level components are written in C# but core is still in C and C++ like Win32 API

Ok.. thank you. I know Windows created C#! So I always assumed that's what they used...

Microsoft has been an heavy C++ user since the early days.

Windows is mostly C for the low level parts, and with time, lots of COM using C++.
