Проверьте на ошибки! Hello Bill. How are you? I recently heard that you started working on a new operating system windows. I think your invention you made in 1981 changed the way people thought about Computers. At the time when you did your invention is very popular among people who have had the computer. But for today Computers are in almost every human being and your operating system is outdated and needs updating. So I wish you success in your work and that your new work became popular. goodbye.
