Windows 8 Start Screen:
When clicking Desktop you get the main Windows traditional Desktop minus the traditional start menu button. The way to think of it is the menu is now a whole screen rather than a small menu in the bottom left corner.
The major difference you notice here is the missing start menu and for the first week or two it may drive you a bit nutty as we retain our brain not to go to the bottom right corner and try and learn to use the WINKEY and then start to type the name of your app eg iTunes you will find it is actually better than using a mouse to the start menu as most people do in Windows 7.
From the Start menu you can right click anywhere in the open space on the start screen and you get an all APPS menu:
Clicking it brings up all programs and applications that are installed on the computer, this then allows you to further customise the start screen. One of the best things to do is to arrange your most commonly used apps to the left of the start menu.
When right clicking on one of the apps you have a range of options to select, such as pinning the program to the desktop task bar or pinning the program to the start screen. One of the first things I did was pin my top 5 applications to the taskbar.
To move your apps around simply click and hold down the left mouse button and drag the app to the desired group. Group as you pin apps into groups or create new groups:
If pinning options are not available that simply means that the app/program has already been pinned. Though you will then get the option to unpin the app/program.
To customise your start menu, right click on an app to see the available options:
When clicking on the minus button on the far side right hand side of the scroll bar you get a groups menu. This allows you to move the Windows 8 start groups around; if you right click on these groups you then have the opportunity to name the group to something of your choice:
The group menu:
Right clicking a group:
When on the traditional desktop mode, move the mouse to the bottom right hand corner and right click. Here you will find a contextual menu with system options. This is very useful when managing a Windows 8 PC:
Moving your mouse to the top right hand side of the screen you are presented with the charms menu. You can also press WINKEY+C to open the charms menu:
To shut down the computer click on the settings button on the Charms menu and then press power – you will be given a few options, such as log off, sleep, and shutdown:
