How can I remove all file associations for Microsoft Office 2007 without uninstalling it?

In addition, is it possible to install Office 2007 and not create any file associations?


If you're in windows 7, open your start menu and click on "Default Programs". Now click on "Associate a file type...".

From here you can remap, but not remove, any file associations. Here is a list of Office 2007 file extensions, which will come in handy.

If you want completely unassociate a filetype, you must use a third party tool, or delve into the registry. I prefer this little freeware tool called unassoc.

  • Are there any command line tools for both win xp and win 7 to do same thing as unassoc ? – Primoz Nov 5 '11 at 17:07
  1. Back up HKEY_CURRENT_USERS\Software\Classes and HKEY_LOCAL_MACHINE\Software\Classes before you install, then restore those keys after install. That should reset your file extensions

  2. Do what Paul said and delete them after install. This is a much safer option. Additionally Default Programs Editor is a point and click option to delete Default Programs associations.
