Windows 10: Defender not Running Regular Scan

    I fixed this problem by making a task from scratch in the Task Scheduler Library folder in Task Scheduler. Just set it up to run "C:\Program Files\Windows Defender\MpCmdRun.exe" Scan -Schedulejob, and works every time I tested it. Is there any problems with doing it this way?

    No but you should disable the auto maintenance scan task otherwise it will try to run as well. Find that one in Task Scheduler Library>Microsoft>Windows>Windows Defender. Third task.

    I had to do the same thing - create a scheduled task to perform a scan. Its working ok.

    This was reported quite a while ago. If you want to reliably run a Defender scan in Win 10 AU you need to create a task. As I said above, if you did create a manual task you should disable the automatic maintenance task otherwise you will have scans running too often,

    But the reason I created the scheduled task is because automatic maintenance is not working. So I won't have tasks running too often.
    If auto maintenance worked I wouldn't bother with a manual task.

    It will work, but only if the specific conditions are met.

    It does not work. Refer post #46.
    The other 3 auto tasks run, but, the auto task for scheduled maintenance does not run.

    I worked on this issue on another forum and know exactly what the issue is. If you've got it working how you want that's what counts. But I am fairly confident that the auto scan would run if given the right conditions. And my advice to disable the auto maintenance scan if you have created a manual task is good.

    After I enabled the task, I just assumed it was running..
    Until just half an hour ago when I noticed it hadn't been running for over a month (on my server, of all things! And -ONLY- on my server)

    Any attempts to make it run normally failed.. But I finally solved it
    Instead of having it run the actual program, I had it run a bat file with the one line:
    @"C:\Program Files\Windows Defender\MpCmdRun.exe" Scan -ScheduleJob

    Now it suddenly works perfectly (for all the test I've done since I figured this out 15 minutes ago, mind you!)

    I also set it to not only run at a specific time, but also upon login. Not sure if connecting through RDP counts as a login.

    I hope this helps, I registered to post this.. And I hope it helps.
    I'll keep an eye on it and update this post in a week, or if things fail to run..
