In Windows XP, I was able to access to the start menu and organize the programs into their own folders. I could have a game folder and put all the games into it. This made for a much easier display of the programs and not having to go into separate columns to list the programs. How can you do the same thing in Windows 7?
All you need to do is alt-click "All Programs" and select either "Open" to rearrange programs in your user account only, or "Open All Users" to rearrange programs installed for all user accounts. Note that if you have a folder by the same name in both your start menu and the global ("All Users") start menu, they will be merged automatically when the start menu is displayed.
Windows 7 doesn't allow you to change back to your classical windows Start Menu. However, you can organize your program list. It's actually located in the following directory:
C:\Users\<USERNAME>\AppData\Roaming\Microsoft\Windows\Start Menu or %APPDATA%\Microsoft\Windows\Start Menu
If you still want your classic Start Menu and don't mind installing 3rd party software, you should take a look at Classic Shell.
