 The actual trading platforms, all those sort of systems, aren't usually on Windows, so those weren't impacted, but the traders put those trades through, used Windows to actually trade those stocks and shares, so they were obviously impacted as well.

And then the London Stock Exchange had some issues with its news service, because, again, they're running on Windows.
