Windows operating systems are by far the most popular in the world. Approximately 90% of personal computers use some type of Microsoft operating system. An evolution of Windows software since the mid 1980 s has continued to provide a PC operating system with a simple interface and enhancements to keep abreast of hardware advances and new computing capabilities. Microsoft s founders are Bill Gates and Paul Allen. I. Windows 7. Windows 7 was introduced in late 2009. Windows 7 had many new enhancements and was intended to provide all the remedies to the flaws identified in Windows Vista. Windows 7 introduced a new interface called Aeroglass. II. Windows 8 Microsoft s current operating system has many new modern enhancements, including the new Metro interface. Windows 8 has not been well received by Industry, almost instantly after its release Microsoft was back to work on a new Windows version. III. Starting Windows 7 - Windows is loaded into memory simply by turning on your computer (booting). Once you launch Windows, the Windows desktop displays on the monitor. Beginning with Windows Vista, the operational emphasis shifted from the desktop to the Start menu. By default, when you install Windows 7, only 1 icon appears on the desktop (the recycle bin). Why the deemphasis of operating from the desktop? The following are basic Windows components: COSC 1301 Spring 2015 1
A. Desktop - The desktop contains icons that represent tasks, commands, programs, files, or shortcuts.

TSRs are programs running behind the scenes or in the background such as virus detection software, volume control, time, etc. C. Start button when selected, displays the Start menu. The Start menu provides access to everything not on the Desktop, programs, help information, change program settings, shut down your computer, and also provides access to other menus containing tasks and functions. The Start menu includes 2 columns: The one on the left contains the pinned items list (top part) and the most frequently accessed programs list. The column on the right is the actual Start menu. 1. Pinned items list by default displays your default browser and default email application. The content of the Pinned Items list can be modified. COSC 1301 Spring 2015 2

Windows - all active Window's objects appear within a rectangular work area called a window. The window encompasses a program or task and in essence is the desktop workspace allotted for that particular operation. The content of any window may be altered by selecting options from the View menu. The structure or components of certain windows can be altered by selecting options from the "Organize" button on the toolbar. Windows 7 Explorer View Other window contents include: 1.

Windows will display all open applications as thumbnails in the middle of the screen. Continuously pressing the TAB key places a rectangle around a different thumbnail.
