[Tool] Un-associate file types in Windows Vista

There is a tool that greatly facilitates and automates this task. The download for this tool can be found here:

• Let's say that you accidentally associated a file extension with an application and that you want to delete the association.
  
  
• Run the unassociate tool, select the wrong file association and either delete the user association or delete the whole file type from the system. The necessary registry changes will be done automatically.
