Stop Access 2007 from configuring on every start

If you have Access 2007 and an earlier version installed, Office goes through a ridiculous "configuration" process when you switch between the versions. Sometimes it does this every time you open Access 2007 - you can stop it by deleting this registry key:

HKEY_CURRENT_USER\Software\Classes\Access.Application

If you want to stop the configuration process for Office in general, see this post.
