In the newly released Windows 8, due its new user interface design, among other things, locating the shutdown (plus’ reboot’ and ‘sleep’) button can also be a little bit difficult. There are many ways to do it. But the easiest is to move your mouse over to the right edge of the screen (from the desktop or the ‘Start’ screen) and then bring it down.
As soon as you do that, you will be greeted with the right-side bar, and from that, you have to click on the ‘Settings’ icon (at the bottom), and then the ‘Power’ icon from the next window (also located at the bottom), and then make your selection.
Though once get used to it, it is not such a burden after all. Still, if you are looking for a utility that lets you quickly access ‘Shutdown’, ‘Reboot’, ‘Sleep’, ‘Sign out’ and ‘Switch User’ functions (from the desktop or the ‘Start’ screen), then this utility called ‘Quick Shutdown’ might come in handy.
When installing, it automatically adds its icon to the ‘Start’ screen, and you can also add a shortcut on the desktop too.
However, because having its icon on the taskbar is very useful, once it adds an icon to the ‘Start’ screen, open the ‘Start’ screen, select its icon and right click on it. Then from the menu at the bottom, choose ‘Pin to Taskbar’ option.
This will add its icon to the taskbar of your desktop. So as you can see from the screenshots, once clicked on its icon (‘S’), it simply opens the built in tool in Windows 8 that lets you access the above mentioned functions.

Note: While trying to install it, Windows 8 should give you a warning (as far as I can tell, it is pretty safe. But please use it at your own risk).
If you want to continue the installation, then click on the ‘More info’ text on that message and then click ‘Run anyway’ button. Then follow the above mentioned steps to add its icon to the taskbar.
