Restore Vista compressed file association

Recently I lost the ability to expand zip files as compressed folders in Vista. a quick search of the web and I found this:

  1. At the start prompt enter “cmd /c assoc .zip=CompressedFolder
  2. If necessary, Open regedit, navigate to the above path and delete the UserChoice node
  3. Restart Windows

remember editing the registry can be dangerous, so always backup first or create a restore point.
