Ok, this one isnt exactly a repair tool, but it is very useful to have this in your kit. As some of you may already know, the new Microsoft Office 2007 no longer uses the .doc format for documents. By default, it now uses a new extention called .docx.

Saving in the new format isnt a problem if you actually have Office 2007, but when people using older copies of Office try and open a .docx file, they cant. The Office 2007 compatibility pack allows those with older versions to open, edit, and save documents, workbooks, and presentations in the file formats new to Microsoft Office Word, Excel, and PowerPoint 2007.
