Windows 10: Why is "Scan with Windows Defender" blocked by IT on a personal computer?

Your IT administrator has limited access to some areas of this app,and the item you tried to access is not available . Contact IT helpdesk for more information. This is the message I get when I try to scan a drive using windows defender (right click and scan using windows defender option).


The only thing that changed between it working and not was the April 2018 update. This is my own computer and I am the system administrator.
I do have periodic scanning turned on.

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.

 

Remove Scan with Windows Defender

I've updated step 3 in OPTION ONE below. It should work for you now. *Smile

Scan with Windows Defender Context Menu - Add in Windows 10

 

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..
