Which is the oldest version of the computer system?

Windows 1.0 is an operating system released by Microsoft on November 20, 1985. This system is Microsoft's first attempt at a user graphical interface for a personal computer operating platform, and it is also the first Windows operating system version released by Microsoft.

Windows 1.0 is based on the MS-DOS operating system. In fact, it is not an operating system itself. At most, it is based on applications running under pure DOS at the time. The subsequent Windows 2.x and Windows 3.x are still DOS-based operating systems (both are also DOS-based applications). The Windows 1.0 operating system was Microsoft's first attempt at a graphical user interface for a personal computer operating platform. It was also based on the MS-DOS operating system. The graphical interface of Windows 1.0 basically announced the end of the DOS operating system.

Interface Manager is not the real Windows 1.0. In 1983, Microsoft announced that it would start designing Windows. The design work of Windows 1.0 took 55 developers a full year until November 20, 1985. It has just been officially released. It is based on MS-DOS2.0, and the interface has been greatly improved compared to the interface manager. The role of the mouse in Windows 1.0 received special attention, and users could complete most operations by clicking the mouse. Windows 1.0 comes with some simple applications, including calendar, notepad, calculator, etc. In short, looking at Windows 1.0 at that time, people always felt that it was like a PDA, but this was already quite attractive at the time. Another notable feature of Windows 1.0 is that it allows users to execute multiple programs at the same time and switch between programs, which is unimaginable for DOS.

Windows 1.0 can display 256 colors, and the window can be resized arbitrarily. Another important program in Windows 1.x is the Control Panel, which has clear definitions of drivers and virtual memory. However, the functionality is very limited.
