    Windows Defender Definition Updates.

    Thank you Elba for the prompt reply. However, there is a problem: In "Control Panel" under the "Programs and Features" page > "View Installed Updates" the " Windows Defender Definition Updates" are NOT listed. Consequently, I cannot delete/uninstall them.
    The same thing happens when I use "Settings" >" Updates & Security" > "View Update History". Here the Definition Updates are all listed but I can't uninstall them either. Any other suggestions?

    Thanks again, Fred
