@thomasfuchs until 2013 the ISS was running WinXP on its main UI computer. Yes, with the old NTFS that will be happy to mega corrupt if the power is lost at an inconvenient moment or a stray cosmic ray decides to be extra annoying.

Having horrible unreliable UI that works with the very redundant and reliable hardware and firmware that actually runs the vessel seems to be a trend in the space industry. Electron-based rocket control still takes the cake as the most horrifying example I know of though.
