When you use programs, they show up in pretty much the same place as Win7 (upper left, moving down).
You have the opportunity to make little tiles out of them for quick access.
Basically you can now add unlimited shortcuts to the start menu in stead of the 10 Win7 limits you to.
If you make tiny tiles out of them, you can add a shitload in the same amount of space Win7 uses.
Really, if you are this inflexible in your use of a system, you shouldn't upgrade. Or at least do some basic research.
