Hi, According to your description, this error code generates when Windows updates. May I know the related event logs that may contain additional troubleshooting information? Please post the related logs in your post. First, please run services.msc, and ensure the Background Intelligent Transfer Service is started. Second, you better run sfc /scannow (without the quotes) command under an Administrator Command Prompt window.
