Anyone using a non-touchscreen device and Windows 8 tends to miss the old Start button. We have always had a few programs to restore the Windows 7 style start menu but spent some time finding the best and free programs for you.

At the bottom you will find one that just makes using what you have easier and the last one is for those who like the Windows 8 UI and want it on their Windows 7, Vista or XP machine.
