Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

Resolves an issue that might occur with the "Enhanced Write Filter (EWF)".

• KB2539566 fixes the following issues:
  • The Enhanced Write Filter (EWF) Provider will crash if all EWF volumes have their Overlays disabled and the user tries to subscribe to a EwfOverlayStoreConfiguration event query. Until the new EWF Provider instance is created, all other commands will fail. Expected return code in this case would be 0x80070057 = ERROR_INVALID_PARAMETER. If a crash has occurred, the return code is 0x80041004 = WBEM_E_PROVIDER_FAILURE.
  • The event notification threshold values in EWF are inverted.
