The biggest complaint from users new to Windows 8 is the lack of a Start Menu. Once you get used to it the Start Screen is a more than adequate replacement, but if you must have a Start Menu, here is how to add the Start Menu to Windows 8.
With the Start Menu officially gone, you're forced to use the new Modern UI Start screen instead. You'll probably find you get used to it more quickly than you were expecting. However, if you really want to stick with the old system, or if you want to maintain a consistent interface between mixed Windows 8 and Windows 7 PCs, you can use a third-party Start Menu program to bring back its functionality.
One such program is Start8 from Stardock. This utility costs $4.99 (around £3) but offers a highly configurable Start menu which can be displayed in either a traditional Windows 7 format or as a smaller pop-up version of the Windows 8 Start screen. It also gives you the option of automatically going straight to the desktop when you boot up.
You can also run XP Mode in Windows 8. It's a bit more involved, but we show you how in our article: How to migrate Windows XP Mode to Windows 8.
