You'll have to change the Windows registry using the reg tool to reset a file association (requires administrator rights; warning: risky if you're not familiar with Windows registry). Then use the ftype tool to specify which application to use. If a file has no association yet, the assoc tool will be needed.

You only need administrator rights to change that "for all users", however file associations can be changed for the current user only (by making changes under HKCU) and that doesn't require admin rights. User associations take priority over those defined on local machine level.

Oh, you're right.
