Have you found a fix for this one? I have exactly the same problem except, without thinking, I installed Office 2007 before uninstalling the 2010 trial version.
The icon is the blank one with lines and the letters docx, opens correctly and when looking at the properties the correct icon appears for Microsoft Office Word. All the other Office file extensions are associating with the right icon.
The machine is a new Dell with Windows 7 Professional 64 bit.
It is driving me mad.
