The quick access toolbar (shown below) is the little bar at the top of most Microsoft Office 2007 / 2010 applications.
Some power users like to customise this toolbar to add extra icons to it.
If you use redirected appdata or roaming profiles you will most likely find that these changes do not save. This is because Microsoft decided to turn this behaviour off by default and store these changes elsewhere.
Thankfully you can turn this back on.
