Many PC users are content to use the free antivirus that’s built-in to Microsoft Windows: Microsoft Defender Antivirus. Some still call it Windows Defender, but in any case, you can get to it by clicking on the white or blue shield that lives near your system clock.
But some users are finding that they cannot enter that shield icon, after certain Windows Updates. Some Microsoft upgrades break that icon, and won’t let you see your protection software anymore. If this happens to you, there’s a quick fix for that:
- Click the Start button and use the Windows Search function to look for “Powershell”. When you find it, right-click it and select Run as Administrator.
- Copy and paste the following chunk of text into the Powershell window and then press Enter on your keyboard:
Set-ExecutionPolicy Unrestricted
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
- When the operation appears to be done, close Powershell and reboot your computer. Check the Windows Security Center icon, and it should now open easily for you.
If this kind of repair is above your paygrade, feel free to call me and I can fix this for you!
