What program do you use to edit file associations in Vista and Windows 7?

We all know that Vista and Windows 7 doesn't let you specify custom extensions or customize them to your liking. What program do you use to edit file associations in Vista and Windows 7?

EDIT:


Just to be more clear, I'm looking for a program which lets you:

  • Create new extensions (I am aware of the Open With > Set As Default).
  • Customize the Icon
  • Customize the file type name
  • Allows the creation of custom actions
  • Repair any non-working extensions

Presently, the Windows Vista/7 extension manager doesn't let you do any of those actions.


Solution 1:

Default Programs Editor was created for this purpose! From the site:

File Type Settings:

  • Add, Edit, and Delete context menu items
  • Edit file type information (such as icon and description)
  • Change an extension's associated file type

It also does Autoplay handler editing, and Default Programs editing. And it installs as a Control Panel applet, which makes it discoverable from Windows Search, so you can forget about it until you need it.

Also, it doesn't require administrative privileges for most operations (but it is UAC compatible).

(In the interest of full disclosure, I wrote this program!)

Solution 2:

FileTypesMan from NirSoft fulfills all your requirements.
