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.

 

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..

 

Cannot schedule scans for Windows Defender

Hi Nathaniel,

As per the description, you are experiencing issue with you can’t schedule scans for Windows defender and getting error message pop ups: “The combination of properties that task is using is not compatible with the scheduling
engine” on the system.

I certainly understand your concern and appreciate all your efforts in trying to fix this issue.

There could be a possibility that this issue might have occurred if there are corruptions in Windows defender services.

I would suggest you to try the following methods and check if that helps.

Method 1:

You can enable the Windows Defender either from control panel or from services.

Step 1:
Enable Windows Defender from control panel

• Press Windows + X, Click on control panel.
• On right top corner click on View and then choose large items.
• Now from the list click on Windows Defender and try to enable it.

If not try to enable it from services.

Step 2:
Enable Windows Defender from services.msc.

• Press Windows + R, to open run prompt.
• Type services.msc and press enter to open services list.
• Under services look from Windows defender service and start the service and set to automatic.

Note: If the services are already started, then click on the option that says: “Restart the service” and check if that helps.

If the issue persists, follow method 2

Method 2:

How to use the System File Checker tool to repair missing or corrupted system files, please follow the steps in the link provided below.
