Microsoft Office 2007 is a popular document producing application, which has a number of different programs attached to it such as Word, Excel, PowerPoint and OneNote. All of these programs make the Microsoft Office 2007 application. A step up from its predecessor Office 2003, this application has a better GUI (Graphical User Interface) and a lot more features, which make your Office 2007 experience a lot better. Although this program is very popular and has helped many people create some fantastic presentations or proposals, there are claims that it actually slows your computer down and puts a herd of damaged and corrupt files into the registry. The registry is where all the important files and settings are held and are arranged in hierarchical order so the computer can operate as fast as possible. However with all of these damaged and corrupt files that are in the registry then it makes the computer work a lot harder, which results in a slow computer.
