    Hi,
    You can manually download the latest update from the link provided above:
    https://www.microsoft.com/en-us/wdsi/defenderupdates

    choose security intelligence files that matches the products and platforms, the product download links point to an executable file named mpam-fe.exe, mpam-feX64.exe, or mpas-fe.exe (used by older antispyware solutions). Simply launch the file to manually install the latest security intelligence.

    For more information, see Manage Windows Defender Antivirus updates and apply baselines.

    Best regards.
