Replaces the "File Types" dialog that went missing in Vista:

Missing in Vista!

Manually add extension and file type information
Change a file type's description
Change a file type's icon
Change an extension's associated file type
Add/Edit/Delete an extension's default association
Add/Edit/Delete other entries on the file's context menu
Preserve verb precedence hierarchy
View shell extension entries on the context menu
Remove 'Default Programs' association that Windows likes to make annoying to change
Add/Edit/Delete your own autoplay handlers
Change which autoplay options are available for users
Disable that "Search web for unknown extension" dialog
Single .exe utility, no installation

On top of all that, here are some bonus features:

Make changes direct to the registry, or export them as .reg files for easy distribution
Designed for Vista, with UAC support, so you can painlessly run as a standard user
Also should work on XP (minus some parts best configured with TweakXP)
Make changes to your user account, or the machine default, or both

Here are a couple how-to's to get a feel for it. Contact me if you're having trouble and need something explained, or leave a comment on the blog.

The information url comment in exported .reg files has been updated to this program's own page instead of it's blog category.

A couple of additional minor UI adjustments (including a misspelled word in the error dialog- whoops!).
Added a dialog to enable the deletion of both an extensions and ProgID's.
Fixed an rare bug that caused an immediate crash (both XP and Vista) based on information from online crash reports.
Fixed a bug where extensions without ProgID's would have a blank Friendly Type Name instead of EXT File, which is what Windows Explorer shows.
