Hello. You can use the Ribbon customizer for Office 2007, or set the document format to rtf for Word and excel 2003 file type for excel. Or, you may decide to uninstall Office 2007 and reinstall 2003. Sharing documents? No problem because rtf format can be read by many software from the old Write (used in Windows 3.x) to Word 2007. Or, you may use the following sites to convert among many formats. http://zamzar.com http://www.convertfiles.com
