One of the major reasons why most Windows 8 users are extremely frustrated with the operating system was the lack of familiarity when performing even the basic tasks. Windows 8 users find trouble shutting down or restarting their PC because Microsoft has neatly tucked away the option in a different place.
The reason why the Restart Windows 8 and Shutdown Windows 8 options are hidden is that Microsoft designed the OS in a way that is similar to tablet users. This means Microsoft encourages its users to enter a low-power state or hibernate, instead of completely powering down their computer. Hence, you can change the setting to switch to low power mode when you close the lid. However, this design is flawed because desktop users were not able to power down the OS the usual way. You will have to open up the Charms bar in order to switch off your computer.
The entire UI (user interface) of Windows 8 OS has been altered to lean in favor of touch screen users. When doing so, Microsoft kept its keyboard and mouse users in the dark by creating an interface that is ridiculously difficult to perform using a mouse. Although Microsoft made some attempts at correcting it in Windows 8.1, the entire UI is still a mess and inoperable for most users that are accustomed to working in Windows desktop computers.
One of the methods of shutting down Windows 8 is to bring your mouse to the upper-right-corner in order to bring up the Charms menu. If you are using a tablet, you can merely swipe from the right to bring the Charms menu. A definite shortcut to bringing the Charms bar is by pressing the Windows key + C button. The shut down option is nested inside the Settings button of the Charms bar.
For faster access to the Charms settings, you can press down Windows key + 1 on your keyboard and select the Shut down option. Another workaround to performing the action fast is by creating shortcuts for Shutdown and Restart and then pin them to the desktop. By doing so, you will be able to shut-down the computer at the press of a button located in the desktop. Fortunately, the Shutdown Windows 8 and the Restart Windows 8 option are located in the same place, avoiding the need to go hunting for the option elsewhere!
