  • Hi Dinesh,

    Welcome to MSDN forum.

    According to your description, the error code “0x8024401C” often means the Windows Update service could not be contacted. please try to disable WSUS settings and restart your Windows Update service with the following steps:

    #1. Type regedit in the start search box and run it as Administrator;

    #2. Navigate to Computer\HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU;

    #3. Change the value of “UseWUServer”key from 1 to 0 to disable the WSUS server, then close the registry editor;

    #4. Open the Services Console by entering services.msc in the start search box;

    #5. Locate and right-click to Restart the Windows Update Service.

    After the above performance, you could try to turn on .NET Framework 3.5 from Control Panel again.

    If the issue still persists, I suppose your system files are damaged. Please use the DISM tool to fix Windows Update errors.

    Hope it helps and any feedback will be expected.

    Best Regards,

  • Can you install any Windows updates on the system?
    Is the system using a WSUS server to get updates?
