5 years ago I was called out to a company in Sydney, Australia that ran some mail (paper!) processing software on a machine running Windows 98. They sent out big numbers of lottery tickets around the world.

Another one was a textile manufacturing company running Windows 95. The systems were attached to the internet not because they wanted them to be, but because the admins didn’t have the networking skills to split up the network like that.

I wouldn’t be surprised if they ran some of these online updates on those systems.
