"Windows" is a registered trademark of the Microsoft corporation. It represents an operating system used mainly on personal computers.

Largely because it was adopted by most companies of the world, Windows is the most commonly used operating system in households and businesses.

Windows comes in many versions. At the time we are creating this course, the version called "Windows 10" is the current version, so this content is based on that version of Windows. However, most of the content is also valid for earlier versions, and will likely remain valid for some future versions.

In the video below we take an overview of this course and then the lesson describes hardware and software, and how all computers work.


Note: I strongly suggest you view all our videos in full screen mode: click the icon in the lower right corner of the video area (it shows four arrows pointing to the corners of the screen). When you are done, the Esc ("escape") key returns you to regular mode.
