So your PowerPoint toolbars have exploded and you need to reset them with your backup .pcb file (file that contains your customized toolbar settings). But you have just upgraded to Vista and it is no where to be found!
Here is where you need to go:
C: >> Users >> (Your Name/Account) >> App Data (will need to be able to view hidden folders) >> Roaming >> Microsoft >> PowerPoint
