  1. Windows Defender update stuck on "0% Downloading"


    Good Morning


    For the last 3 weeks I for some reason can't update windows Defender. It's stuck on downloading.


    Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.275.1086.0)
    Status: Downloading - 0%


    Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.259.652.0)
    Status: Downloading - 0%


    Once the update doesn't work I get the following error message:


    Error 0x80070003 while downloading update for Windows Defender.



    I've tried everything also methods below:


    Method 1:

    I suggest you to run the Windows Update troubleshooter and check if it helps.

    • Press Windows key, type troubleshooter in the search box and then press enter.
    • Select Troubleshooting. Click on view all and select Windows Update troubleshooter and follow the on-screen instructions.

    Try below given method if issue persist.


    Method 2:

    If issue persist I suggest you to reset Windows Update component. Kindly follow the below given steps.



    • Press Windows key + X, select Command prompt (Admin) to bring up elevated Command prompt.
    • Stop the BITS service, the Windows Update service, and the Cryptographic service. To do this, at a command prompt, type the following commands. Make sure that you press Enter after you type each command.
      • net stop bits
      • net stop wuauserv
      • net stop appidsvc
      • net stop cryptsvc
    • Rename the softare distribution folders backup copies. To do this, at a command prompt, type the following commands. Make sure that you press Enter after you type each command.
      • Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak

    • Restart your PC and check if it works.

    Method 3:

    The system file may have got corrupted due to corruption in system file. I suggest you to try the following steps:

    • Open command prompt by pressing Windows key + X and selecting “Command prompt admin”.
    • In command prompt, type the following commands and press Enter after each command:

    DISM.exe /Online /Cleanup-image /Scanhealth

    DISM.exe /Online /Cleanup-image /Restorehealth



    • Close the command prompt and restart the PC and check if it works.

    :)

    Windows Update still hasn't successfully updated Defender, however by chance I spotted that Defender itself reports as having updated today.
