    Definitely some form of UNIX, the flavour which included C and not C-sharp or C++.

        They don't use one OS but up to 16 for various functions - most OS's are classified to prevent viruses.
        E.G. the system for mapping the earth is totally different to the system used for environment control.
        Astronauts use laptops and upgrade the onboard systems regularly,
        Systems are from the USA,Russia, England etc.
        Hope this helps

          One thing I can see from the "virus problem": Since MS is discontinuing support for XP, there's probably not going to be many updates in the future. And most newer MS operating systems require newer hardware, while most Linuxes can run on 10+ year old hardware just fine. On the space station upgrading hardware is exorbitantly expensive (think of the cost per payload for taking stuff to space).

          As an aside, I also think Linux isn't the full answer. They only mention "key functions", i.e. probably only some PC's are migrated.

              User systems (onboard laptops etc.) on the Space Station runs Linux. Used to be WinXP. SOURCE

              The Space station itself probably runs on VERTEX/VxWorks as Curiosity and a few other space projects do.

              Curiosity Link

              VxWorks Link

              In the early 90s I had my hands on VERTEX for a while. I was told to study it. When we wanted to start a project and called the VRTX helpdesk with our serial number and all we were told that we have an illegal copy, the real owner was some military type company in the UK. That was the end of it. The software came on floppy disks and was the entire operating system in Assembler code with manuals on how to use it. They company paid R 50 000 for it in the 90s !. Pity I didn't make copies.
