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.
HKEY_LOCAL_MACHINE\Software\Classes before you install, then restore those keys after install. That should reset your file extensions
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.
