One of the biggest problems with some programs is the way that they are constantly changing their interface between versions meaning that once ou upgrade to the new version you need to start learning the program all over again because everything works differently and nothing is where you expect it to be.
One such example of this is with Microsoft Office 2007 where the standard menus that everyone using prior versions of office (and many other programs for that matter) know quite well with a new 'ribbon' system where it takes forever to find any of the options you need.
Fortunately, Microsoft provided an option for being able to add additional tabs to their ribbon interface and a number of people have created ribbons for the office programs that correspond to the old menu system. There are a variety of such ribbons some of which you have to pay for and others such as the one from ubit which are free. The main difference between the free and paid versions appears to be that the ones you pay for also give you the ability to turn off all the other unwanted ribbons so as to just leave the one with the standard interface while the free ones only add the new ribbon providing the old interface without changing any of the others.
This new arrangement is far less flexible and less user friendly than the old system but appears to be the best that can be done without switching back to the older version of the program. It is the only practical alternative though if you are required to be running Microsoft Office 2007 or later.
The other alternative if you can choose what programs you run is to switch to using the latest version of Open Office which provides all the same functionality as the latest Microsoft Office but with a proper user interface instead of the silly ribbon thing.
