Windows 11's Windows Security App can't open.
Hello,Suggest try the following steps:
- Open PowerShell by using Administrator rights
- Copy and paste Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage to the PowerShell window and press enter
- Close the PowerShell and retry
JianYu this solution doesn't work for me
tried other solutions like Windows Security in Windows 11 not opening or working (thewindowsclub.com)
except for only reinstallation on my side. Do you have any other solution? I bit doubtful windows defender then install 3rd party internet security ie, Kaspersky
karthikshaindia If this solution do not work for you, I think you can just follow the reinstall step based on the link you shared or maybe you can install 3rd party antivirus software like you said if you own a license key to activate the software 😊
Did not eork for me

Mine works now I assume it was a previous update that fixed it?

Did you make sure to run Powershell as administrator?
Thank you,
I checked out your link "Windows Security in Windows 11 not opening or working (thewindowsclub.com)"
I did the first option "Reinstall using PowerShell Command" and it looked a little scary, but this method worked for me and fixed it...
Set-ExecutionPolicy Unrestricted
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}- resetting the app worked for me
