Microsoft has removed the Start Menu since version 8 of the Windows operating system. The Start button at the bottom-left corner of the screen now acts as a toggle between Windows Desktop and the Metro UI interface.
If you are using MS Windows 8.1 and you miss the Start Menu in previous versions of MS Windows, you can get it back with 3rd party software.
I use IObit Start Menu 8 to achieve this, as it is free, and very easy to customize and use.
This is what you can get with IObit Start Menu 8 installed in Windows 8.1:
The appearance of Start Menu can be configured to use the Default Theme, Classic Windows 7 Theme, or the Windows 8 Theme.
You can also select your favourite Start Button, as it is configurable.
Similar to the Start Menu in Windows 7, you can customize how the links, icons and menus look and behave on this Start Menu.
With this, you can get back your user experience in using Windows operating system the same style as before.
