Starting with the easy stuff:
QUICK LAUNCH [CUSTOMIZATION]
I went to "Start>Help>Index" and typed "Custom" [the beginning of Customize or Customizing (because you want to customize something)] and found "Customizing the Taskbar".
Two options were found.
The most likely looking was "Add a Toolbar to the Desktop or Taskbar".
I think what you want is the "Quick Launch Toolbar".
Try it for yourself.
Once you get the hang of it you won't need to ask others how to find such things.
START MENU [CUSTOMIZATION]
Getting the idea?
Go to "Customizing the Start Menu", then select:
"To add a Program to the Start or Programs menu"
[there are other useful topics to read]
These instructions [not easy to follow] will tell you how to put Word on your Start menu.
I must say that these instructions in Windows Help are as clear as mud, or lets say difficult to visualise.
It all becomes so easy if you use Windows Explorer and are comfortable using it.
The key [to success] is to realise that what shows on the Start Menu is only a reflection of the files shown in Explorer at:
If you put a shortcut to something [an executable file say, Like Winword.exe] in the "C:\Windows\Start Menu" folder, then it appears at the top of the "Start" Menu.
If you create [and name] a FOLDER in "C:\Windows\Start Menu\Programs", then THAT appears in the "Start>Programs" menu.
If you click on it you go nowhere because it is not a shortcut to any file.
If you then put 1 or more shortcuts [to files] in that folder, then THEY will appear in the Start menu in that folder and will activate [apply the default action to] the file that the shortcut points to.
If you don't make a folder, but put the shortcut in "C:\Windows\Start Menu\Programs", then that shortcut [displaying the name you give it] will appear in "Start>Programs".
You can drag any item on the Start Menu to any location on the menu and drop it there.
So you need to find [use the "Find" facility if you don't know where it is] "Winword.exe" in Explorer and make a shortcut to it and place that shortcut in the place of your choice ["C:\Windows\Start Menu\Programs"], so it appears on the Start Menu.
