Windows 10: My windows defender wont open.

When I try to open windows defender it gives me a white screen with the windows defender logo and then just closes later. I also cant open it via hidden icons, I already tried resetting the app but still doesn't work.

Installing Apps on Windows 10 Has Windows Defender Finding Malware

Hi Tommy,

Welcome to the Microsoft Community.

• 
  Is this issue specific to third party apps?
  

I would suggest you to open Windows defender and add exclusions and check if it helps. Follow the steps to add exclusions in windows Defender.

• 
  Type Windows defender settings in the search bar and press enter
  
• 
  Under Exclusions click on Add Exclusion
  

Hope this information helps. Reply to the post with an updated status of the issue so that we can assist you further.

 

Windows Defender wont open!

My OS is Windows 11 Home, Version 21H2

When I click on "Settings>Privacy & security>Windows Security>Open Windows Security" It won't open and prompts a dialogue box "You'll need a new app to open windowsdefender link" and suggests looking for an app in Microsoft store. But Microsoft store says no app found for "windowsdefender"

the words windows and defender are written as a single word.

And the same happens If I click on any of the 7 links in the list on the left side. Pl help, thanks
