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 https://www.thewindowsclub.com/windows-security-not-opening-or-working
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
- resetting the app worked for me
Thank you,
I checked out your link "https://www.thewindowsclub.com/windows-security-not-opening-or-working"
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"}Did you make sure to run Powershell as administrator?
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 😊
