All about Windows

Windows is an operating system designed by Microsoft. The operating system is what allows you to use a computer. Windows comes preloaded on most new personal computers (PCs), which helps to make it the most popular operating system in the world.

Windows makes it possible to complete all types of everyday tasks on your computer. For example, you can use Windows to browse the Internet, check your email, edit digital photos, listen to music, play games, and do much more.

Windows is also used in many offices because it gives you access to productivity tools such as calendars, word processors, and spreadsheets.

Microsoft released the first version of Windows in the mid-1980s. There have been many versions of Windows since then, but the most recent ones include Windows 10 (released in 2015), Windows 8 (2012), Windows 7 (2009), Windows Vista (2007), and Windows XP (2001).

About this tutorial

This tutorial is designed to show you the absolute basics of using a Windows computer, including how to use the desktop, how to open different files and applications, and how to move and resize windows. The information in this tutorial will apply to more recent versions of Windows, including the ones mentioned above. However, once you've learned the basics, you may also want to review one of our version-specific Windows tutorials. Just select the version of Windows that's installed on your computer:

Windows 7

Windows 8

Windows 10

Windows 8 vs. other versions

While most versions of Windows are relatively similar, Windows 8 works very differently from other versions. However, if you have Windows 8 on your computer, you should now be able to upgrade to Windows 10, which is more similar to earlier versions, including Windows 7. We recommend upgrading your computer to Windows 10 if you can. Review our Windows 10 tutorial to learn how.

However, we'll still point out any major differences between Windows 8 and other versions, which means you'll see some Windows 8-specific information from time to time. If your computer uses Windows 8, you'll want to review both this tutorial and our Windows 8 tutorial to learn more about the differences.

Windows is a collection of programs known as an operating system (OS) that controls a PC (personal computer). First produced by Microsoft in November 1985, it has been frequently updated since, as computer memory has got bigger, as processing chips have got faster and, of course, when the internet was invented. Prior to Windows, PCs were operated by a series of text commands.

Windows' key benefits and features

·         Allows the user to interact with the computer (through the keyboard, mouse, microphone, etc.).

·         Controls the storage of data (images, files, music).

·         Controls hardware attached to the computer such as webcams, scanners and printers.

·         Helps to open and close programs (word processors, games, photo editors, etc.), and gives them part of the computer’s memory to allow them to work.

·         Controls what access to a computer different users have and the computer's security.

·         Deals with errors and user instructions, and issues simple error messages.

·         Promotes multitasking by allowing the user to do several things on the computer at once – for example, watch a video while writing a letter.

Other operating systems are available, notably the Apple OS X used in Mac computers. In addition, with the increased use of smartphones, notepads and tablets, there are systems aimed directly at mobile devices. However, most people who learn to use computers do so on a system running Windows.

Windows 7 support ended on January 14, 2020

Microsoft made a commitment to provide 10 years of product support for Windows 7 when it was released on October 22, 2009. This 10-year period has now ended, and Microsoft has discontinued Windows 7 support so that we can focus our investment on supporting newer technologies and great new experiences. The specific end of support day for Windows 7 was January 14, 2020. Technical assistance and software updates from Windows Update that help protect your PC are no longer available for the product. Microsoft strongly recommends that you move to Windows 10 to avoid a situation where you need service or support that is no longer available.
