In May 2009, Microsoft Office 2010 was officially announced by Microsoft to be the successor of the previous Microsoft Office 2007. The initial release took place in June 2010 for Windows and October 2010 for Mac. Some new features were added, some existing features were improved. Some changes were welcomed, a few others were criticized. Microsoft Office 2010 is unique in its own way, but at its core it remains the same as other versions of Microsoft Office, which is a suite of office software allowing you to create different types of documents.
