  Hello

  
  

  Vista has got an automatic update every day for a few days ago but every time the update starts finally fails with this error: "'Code 8E5E0147 Windows Update encountered an unknown error" "

  
  

  What should I do? Vista Help did not help at all. I got the same error.

  
  

  Thank you.

  suiobo,
  Go to Microsoft's download page and select the download appropriate for your operating system, then save it on your PC.  Then, run the update from your PC and see if it will install manually.  If you still have the error and then perform a clean boot and test again.  Let us know the results.
