It has been 37 years since Microsoft introduced the first Windows system in 1985. What are the versions of Windows system in 37 years? In addition, what are the characteristics of these operating systems? Next, as far as Windows is concerned, I will introduce many popular operating systems in detail.

Since the 1990s, the computer equipment we use has undergone many great changes, as has the computer operating system used with it. Among them, Microsoft's flagship operating system, Windows, is perhaps the most familiar product.

Microsoft's first operating system was Windows 1.0, which was released in 1985. Windows 1.0 is Microsoft's first attempt to implement a simple graphical user interface for the PC operating platform, and it is also the first version of Windows operating system released by Microsoft. In fact, Microsoft originally planned to call this product "Interface Manager", but finally named it "Windows" (window) because of the display form of its software.

Windows 2.0, released in 1987, takes advantage of the fast processing speed of Intel 286 processor, expanded memory and the powerful communication ability between multiple applications brought by dynamic data exchange (DDE) technology. Windows 2.0 has greatly enhanced its support for graphics. For example, the desktop icon appears in the operating system for the first time. Users can overlay windows and control the screen layout, and can quickly find the function modules of Windows with the combination keys. In addition, many Windows operating system developers wrote their first Windows application on this platform.

Because of its great progress in interface, humanization and memory management, Windows 3.0 has won great recognition from users and has a very high user utilization rate. According to some data, Windows 3.0 sold more than 10 million copies in the first two weeks of its release.

Windows 95 abandoned its support for the previous generation of x86, and is one of the most successful operating systems in Microsoft's history. In fact, the iconic Start button and Internet Explorer were first introduced in the Windows 95 era. As a result, Microsoft sold more than 7 million copies of the product within five weeks of its launch.

Windows 98 is the desktop operating system launched by Microsoft in the period when the Internet technology ushered in great development. Microsoft called Windows 98 "the first operating system really launched for users". Its features include "plug and play", desktop quick launch bar and auto play function.

Windows Me in 2000 is probably the most unknown Windows operating system. Microsoft has added multimedia services such as Windows Movie Maker, and set Windows recovery function for it. However, at the beginning of its launch, Windows Me was criticized for its cumbersome installation.

Once Windows XP was launched, it was highly praised because of the aesthetic design of the user interface and the smoothness of the system.

Windows Vista is an operating system with innovative historical significance developed by Microsoft, and its kernel version number is Windows NT 6.0. Compared with the Windows XP kernel, this system is almost completely rewritten, and brings users a new user interface and a large number of new functions.

When Windows 7 came out in 2009, the operating system was praised by the outside world. Until now, Windows 7 has been widely used by enterprises and consumers.

The system's unique Metro start interface and touch interaction system are designed to make it easier and faster for people to operate computers daily, and to provide people with an efficient working environment.

On January 21, 2015, Microsoft released a new generation of Windows system in Washington, and said it would provide Windows 7, Windows 8.1, and Windows Phone 8.1 to all devices running Windows 7, Windows 8.1, and Windows Phone 8.1. On July 29, Microsoft released the official version of Windows 10.
