Writer Name: OSearch14 VSS Writer

What’s going on? The account you have designated as the service account for the “Windows Service – SharePoint Server Search” service does not have the correct permissions to the registry keys required for normal operation. By default, this account is the local system or farm account, both of which already have permissions.

The fix:

  1. Open regedt32.exe on the SharePoint application server running search.
  2. Browse to HKLM/System/CurrentControlSet/Services/VSS
  3. Right-click the key VssAccessControl and add a new DWORD (32-bit) value
  4. Name it with the domain\username of the account you have specified as the service account, set the value to 1
  5. Right-click the key Diag and set permissions; add the service account username and grant it full control
  6. At a command prompt run: net stop osearch14. Once the service has stopped, run: net start osearch14.

You can now check the logs and make sure you are no longer getting Event ID 8213 errors.

The generic information for any vss writer application is also available on the german technet site:,WS.10).aspx

As an addendum, you may also receive errors with Event ID 12289:
Volume Shadow Copy Service error: Unexpected error RegOpenKeyExW(-2147483646,SYSTEM\CurrentControlSet\Services\VSS\Diag,...). hr = 0x80070005.

Initializing Writer

Writer Class Id: {0ff1ce14-0201-0000-0000-000000000000}
Writer Name: OSearch14 VSS Writer
Writer Instance ID: {3e52236a-60d3-4ffa-a0ac-22e0f676c972}

You might receive this error if you add the service account value to the VssAccessControl key, but do not also grant them permissions to the Diag key.
