Windows 11 Windows Security options not opening

[Reetom Ghosh]

I installed something from the internet which messed up my windows security settings. Now whenever I access it it asks me to redirect myself to Microsoft store because my PC cannot open the defenders link. I tried installing the thing via powershell but did not work. It is a personal laptop so I am admin. Any help??

It sounds like your system's security settings might have been altered by the program you installed. To address this issue with Windows Defender Security settings not opening properly, you can try the following steps:

   • Open PowerShell as an administrator and run the following command to reinstall Windows Security: Get-AppxPackage *windowsdefender* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}.
   []Restore Windows Security Settings:
   • Go to Settings > Update & Security > Windows Security > Open Windows Security. Check if this method allows you to access Windows Security properly.
   []Run a Full Antivirus Scan:
