    1)Normally this error code occurs when there is a corruption in the component based serving manifest.
    1.1)Go to start menu
    2)Type in like this ‘cmd → Run as administrator
    3)After opening the command prompt, type in the following code
    3.1)sfc /scannow
    4)Press enter on keyboard
    5)The sfc /scannow command scans all protected system files and replaces incorrect version with correct Microsoft versions
    After completing above steps, you will be able to download the available updates for your system
