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
    [-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.zip\UserChoice]
  3. Restart Windows

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