  1. Can't install Defender definition updates...


    Hello folks, As from this morning it seems again something wrong with Windows Updates, particularly with the definition updates. Have already many attepts but seems it doesn't work - error and finally not installing. What is going on here, I have never seen my system not to be able to update its own Defender definitions. Any advices will be appreciated.

    :)

    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

    Windows Defender Definition Updates.

    You should not uninstall Windows Defender Definition updates, they are installed to protect your computer from malicious threats. Please leave them alone.

    You update history will list previous definitions and updates that were installed, thats normal.
