  1. Win Defender fills up hdd's


    HiSo recently, i've encountered some issues with windows defender on several PC'sThe pc's are running a mix of 2016LTSC, and 2021LTSBBoth experience, that \Windows Defender\Scans fills up with 75gb+ up until the drive runs completely out of space.On average, another 1gb is added each day.Disk cleanup doesn't do anything. It only sees some 8mb on win defenderNot possible to boot in safe mode, as I don't have physical access to any of the PC'sAny suggestions to what can be done.Haven't seen this issue before

    Hi Johan,

    It is possible that your

    causing the error message to appear. We recommend that you perform these troubleshooting steps and check if there are any changes:


    • Shutdown
      your
      PC.

    • Unhooked
      the
      HDD
      and
      turn on
      your
      PC.

    • Reconnect
      your
      HDD
      and
      restart
      your
      PC.

    If the issue persists, we suggest that you contact your
