may 11, 1985 - Windows 1.01
Description:
Microsoft Windows 1.01 retails, at a list price of US$99. It's marketed as a graphical user interface that extends the DOS operating system and lets users run several programs at the same time and freely switch among them. But it's not touted as an actual operating system until a decade later.Added to timeline:
