Like many early versions of Microsoft's GUI operating systems, Windows 1.0 was essentially a program that ran on top of DOS. Microsoft did not release the system until two years after its first announcement, leading to suggestions that
Windows was vaporware. The release was a shaky start for the tech giant. Users found the software unstable. However, the point-and-click interface made it easier for new users to operate a computer. The user-friendly nature of Windows also drew interest from customers who might have been intimidated by a command-line interface. Windows 1.0 offered many of the common components found in today's graphical user interface, such as scroll bars and "OK" buttons.
