Brandon has posted the answer to a question that has been driving me mad… why my Office 2007 files, saved in their native formats (.docx, .xlsx, etc) are not displayed when I search for files of type “Document” from my Windows Vista machine.
It appears that the issue is with where 64-bit versions of Windows (XP/2003/Vista) look for information. Brandon goes on to explain:
“This is a known issue with the 64-bit property system, and happens because the 64-bit shell only looks in the 64-bit section of the registry for a set of keys that map file extensions to various “kinds” for filetypes that don’t emit their own “kind” information. Because Office 2007 is a 32-bit application, it registers its kinds in the 32-bit section of the registry, where the shell never sees it.”
Brandon has been kind enough to post a .reg file that will import the Office 2007 file formats into the 64-bit section of the registry, thus allowing these documents to be found.
