I would suggest instead of trying to get the Start Menu back, get used to the Start Screen. If you use the Start Menu like many users, not much will change. For instance:
- If you click in the bottom left corner or press the Windows key to bring up Start
- If you use the Search function of the Start Menu/Screen to search for apps/options
- If you use the Start Menu to get to My Computer/Control Panel/etc, what you do now is right click the bottom left corner. Windows Explorer takes you to My Computer.
The main difference will be where your favorite apps are placed. Instead of having the commonly used programs on the left side of the Start Menu, you get the Start Screen with tiles, and you have to organize them by yourself.
