Back then...
I think they were on Dec/Vax VMS on the ground for SOHO. They later moved to Solaris. And as I was leaving ESA about 10 years ago, starting to get some penguins.
I imagine space craft themselves were and always will be very specialised systems.
Although there were always some windows machines around with stuff like Excel for doing non critical stuff.
If you get a chance to work there, do. It is quite unlike anywhere else I've worked. (Darmstadt in Germany is where the operations centre is, so I guess working there will become more challenging when we leave the EU...)
