Microsoft Windows

Microsoft Windows is an operating system for computers made by the United States-based company Microsoft. Windows is the most popular operating system, being used by almost 51% of desktop and laptop computers. Versions are available all over the world especially in the European Union, United States, Canada, Australia, and the United Kingdom.

 History 
The first version of Windows, Windows 1.0, came out on November 20, 1985. The newest version, Windows 11, came out October 5, 2021. Most personal computers made after 2015 come with Windows 10. However, some older or cheaper personal computers may come with Windows 8.1 or Windows 7.

Windows makes it easier to run programs, also called applications, than MS-DOS did. DOS required typed commands to make the computer do something. However, DOS required correct syntax of each command. Making mistakes caused the computer to usually give an error message and do nothing.

 Design 
Users control their Windows computer by its graphical user interface (GUI). It only needs a keyboard or a mouse to work. In later versions, a touch screen works as well. However, using both a keyboard and a mouse makes many tasks easier. By clicking a few buttons on the screen, Windows helps keep your files safe, and easier to change and move. Versions of Windows after 2005 make it even easier for some users with disabilities because these versions have touch screens. For use of a touch screen, some mobile devices come with Windows. Tablet computers and smartphones such as Microsoft Surface and Microsoft Lumia use Windows.

 Programs 
The following programs are included with Windows:

 WordPad – to write simple documents, typically using words/text.
 Windows Photo Viewer – to look at pictures.
 Microsoft Paint – to make simple drawings or change pictures.
 Microsoft Edge web browser – to use the Internet to look at web pages and download files.
 Windows DVD Player – to watch videos.
 Windows Groove Music – to play and listen to music.

Windows has several kinds of applications available. Popular applications include games, word processors, or additional programs like Adobe Flash Player. Adding new applications to Windows is called "installing". Applications can be bought or purchased on a CD or DVD. Applications can also be downloaded from the Internet. Some internet applications can be downloaded for free, and others can be bought using the internet.

 Criticism 
Many users complain that Windows makes problems for them. Some users complain that Windows made their computers slower when they changed from DOS. Many people also complain about problems that make their computer less safe to use, even though Microsoft tries to fix these problems. Many computer viruses are made to infect computers running Windows since it is such a popular operating system. Windows was the most popular operating system until recently (today mobile operating systems such as Android are more popular).
