The package wine-binfmt (not part of a standard Wine installation) will now
  automatically register Wine as interpreter for Windows executables.  This
  causes Wine to be invoked automatically whenever a matching file is executed.
  (Previously wine-binfmt only installed support for this, but you still needed
  to activate it manually.)
  Warning: This increases the risk of inadvertently launching Windows malware,
  so please make sure that you understand the security risks before installing
  this package.
