I think after windows OS office would be the second thing it would have known in my childhood before than using office 2003.in school times when we were kids I remem er teacher us to tell us aboht windows operating system by microsoft and then about the office.
Office 2007 have introduced many features and helped to implement many good things which they havent in its earlier version and release.today I think 60 percent people must be using office 2007 they have made it so useful.
Am using office 2007 regularly on my daily life some times I have to ise word fkr making documents, or excel to create some important reports and records.the powerpoint helps me to create goos presentations with effects and animations.
So its a very useful product by microsoft and we all must know how to use it.As many of our work will become easily which earlier we nees to do manually now everything microsoft office 2007 do it for me.
