  Hi NubeeW7,

   

  This issue may occur if there are duplicate accounts on the computer.

   

  Please try the following suggestions and see if the issue can be resolved:

   

  Step 1: Backup registry key

  ==============

  1. Click Start, click Run, input "REGEDIT" (without quotation marks) in the Search box and press Enter.

  2. Navigate to the following registry key by expanding the "+" beside the registry tree in the left pane:

   

  HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/CurrentVersion/ProfileList

   

  3. Right click on "ProfileList", click "Export"; please name the file as "RegBackup" (without quotation marks) and then save it to the C:\ drive as a backup.

   

  Note: In case we need to undo the modification, we can double click this RegBackup.reg file to restore the registry key.

   

  Step 2: Delete the duplicate account

  ===============

  1. Click the Start button, type “regedit” (without quotation marks) in the Search box and press Enter.

  2. Navigate to the following registry key by expanding the "+" beside the registry tree in the left pane:

   

  HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/CurrentVersion/ProfileList

   

  3. Delete the duplicate profile list keys there.

  4. Exit the registry editor and reboot the computer to check the results.

   

  Please check if the issue can be resolved.

   

  Regards,

  Linda

  Hi NubeeW7,
  
  Does this issue happen consistently? If so, can you zip and send the contents of <SystemDrive>\Windows\Logs\WindowsBackup to sneham_at_microsoft_dot_com(Remove underscores and replace words with characters wherever possible)?
  
  Thanks,
  Sneha

  Hi
  
  I have this same problem.  I upgraded to Win7 Home Premium from Vista HP.  External HD is fine (works with another computer), cannot back-up using windows backup or 3rd party software (acronis).  Get the same error every time - 0x80070002 Cannot find the file specified.  When this happens it also disables my wireless network adapter and I can only reset adapter by rebooting but computer hangs at "shutting down" and I have to force quit.  On restart (after I get the "windows failed to close properly" page), wifi works.  I tried the fix above to no avail (no duplicate keys to delete).
  
  Thanks

  I encountered the same problem when  using windows backup.  I tried your solution but did not see any duplicate profile list keys.  I am computer savvy nor do I have any confidence in messing around with the registry, but I am running windows 7 64-bit home premium and wondering what happens if I delete all the profiles.  Just a question, if that is a no-no.  Do you think upgrading to windows 7  is the major cause of all these problems?  Thank you for your help

  Hi fschap and BIGnewbie,
  
  Can you zip and send the contents of <SystemDrive>\Windows\Logs\WindowsBackup to sneham_at_microsoft_dot_com(Remove underscores and replace words with characters wherever possible)? This will help us find the root cause of the failure.
