I really like working on Office 2007 in my office as well as at my home. It has a lot of tools and effective user interface. Microsoft is going to launch Office 2013, which is compatible with Win 7 as the minimum OS requirement. Win XP and Vista user either has to upgrade or they won't be able to use it.
Between the 2 MS Office versions, I would recommend Office 2010 as that's the better version with more functionalities for me.
Hi, The latest version on windows is the 2007 version as far as I can see but a new version Office 2010 should be out in April. No it's not free but the student version is reasonably priced at about £80. Copying it from someone else is illegal!!!! If you are stuck for cash then try open office as that is free and compatible with office.
