You may read that these are genuine Japanese Windows error messages. Well they aren't really (Snopes) but they are amusing nonetheless. They have been around for a good while but just in case you haven't read them:

• Your file was so big.
  It might be very useful.
  But now it is gone.
  
  
• The Web site you seek
  Cannot be located, but
  Countless more exist.
  
  
• Chaos reigns within.
  Reflect, repent, and reboot.
  Order shall return.
  
  
• Program aborting:
  Close all that you have worked on.
  You ask far too much.
  
  
• Windows NT crashed.
  I am the Blue Screen of Death.
  No one hears your screams.
  
  
• Yesterday it worked.
  Today it is not working.
  Windows is like that.
  
  
• First snow, then silence.
  This thousand-dollar screen dies
  So beautifully.
  
  
• With searching comes loss
  And the presence of absence:
  "My Novel" not found.
  
  
• The Tao that is seen
  Is not the true Tao-until
  You bring fresh toner.
  
  
• Stay the patient course.
  Of little worth is your ire.
  The network is down.
  
  
• A crash reduces
  Your expensive computer
  To a simple stone.
  
  
• Three things are certain:
  Death, taxes and lost data.
  Guess which has occurred.
  
  
• You step in the stream,
  But the water has moved on.
  This page is not here.
  
  
• Out of memory.
  We wish to hold the whole sky,
  But we never will.
  
  
• Having been erased,
  The document you're seeking
  Must now be retyped.
  
  
• Serious error.
  All shortcuts have disappeared.
  Screen. Mind. Both are blank.
