How to fix Windows Security Dashboard not opening in Windows 11

A known bug in Windows 11 means the Security Centre Dashboard won’t open. Instead of opening, you see an error about needing an app from the Microsoft Store.

You can fix this issue by doing the following:

Step 1: Open the start menu and search for Windows Powershell in Windows 11 or Powershell in Windows 10.

Step 2: Then right-click Windows PowerShell, and choose Run as administrator.

Step 3: In the Powershell window, type the command Set-ExecutionPolicy Unrestricted and then agree with Yes

Step 4: In the PowerShell window, type the command
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}  and hit enter.

Step 5: Command executes. Ignore errors.

Windows Security Dashboard will now open and work normally
