    Windows Defender v4.9


    Hi Folks:

    I googled that search phrase and got some "credible-looking" results from the PC Mag site. But there was no link for a client download on Microsoft's site. For those running Windows Defender on Windows 8.1, what is the latest revision you're running?

    Hello Jody,

    Windows Defender would be updated via Windows Update. I'm currently running version 4.8.207.0 in Windows 8.1.

    Right, but the 4.8 version was also available via a page for the August 2015 Client Update, so I just wondered if one was supposed to exist for v4.9. I guess the answer is "no".

    Thanks for your help Brink.

    As far as I know, not until it decides to come down via Windows Update.

    Windows 10 currently has Antimalware Client version 4.10.14905.1000 of Windows Defender. The rest are the same versions.
