    How do I reduce the processor priority of Defender Scans?


    When I run a full scan on my SSD, Defender can take up to 90% of the processor and some important jobs hardly get a look in.How can I reduce the priority of Defender to make it run in the background, when other tasks aren't trying to use the processor?

    :)

    defender scans

    Hi Ian,

    Thanks for posting your query on Microsoft Community.

    This issue might occur if you have set any task scheduler for Windows Defender.

    I suggest you to delete the task for Windows defender and check if it helps.

    Follow the below steps:


    • Search and open Schedule tasks.

    • In the left-hand menu, open the Task Scheduler Library, then select
      Microsoft >Windows >Windows Defender.

    • Double-click Windows Defender Scheduled Scan.

    • Select the Triggers panel, then select Delete.

    Hope it helps, reply to us with the status of your issue. We will be happy to assist you.

    How do I reduce the processor priority of Defender Scans?

    right click scan in windows defender?


    thanks for that.. i didn't notice the tutorial section :x

    I did the suggested registry change and it's now listed on the desktop context menu.. but all this does is ask if I want to open it, update, or start a scan... I was hoping for the option where you right click a specific file and it will have listed 'scan with windows defender' like other antivirus programs have.. MSE had it. I'll keep looking around to see if I can find it in the meantime..
