Windows 11 Security App Bug Found on by Windows Insiders

But there is a fix for the Windows Security bug that was caused by a recent Windows 11 update Microsoft rolled out last week.


As moves towards a fall launch for , the company is testing the new platform in preview. While some of the benefit of the preview is to test new features, it is also to squash bugs before they reach full production cycles. So, with a current issue in , that is exactly what Microsoft is doing.

Windows 11 testers are seeing an error message form Windows Security that says “You'll need a new app to this windowsdefender link”. Considering the number of reports regarding the message, it seems to be widespread across many Windows Insiders.

It seems a recent (broken) Microsoft update is the cause of the problem. The issue is within the Windows Security app, which is the hub for managing security features across Windows 11, including .

That Microsoft update in question is Windows 11 Build 22000.160, which arrived last week with a new Clock App design and Focus Sessions feature. The errors message is more than an annoyance because it shits off parts of Windows Security.

Specifically, some Insiders cannot access features for firewall & network protection, account protection, and more. It is worth noting it seems it is still possible to view these metrics without the app.


Luckily, there is a fix available for this problem thanks to PowerShell. Here is how you do it:

  • Open Windows using PowerShell
  • Search with administrator access
  • Paste Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
  • Clod the PowerShell window

You should now be able to access Windows Security and use it properly.

Of course, there is nothing uncommon about a preview platform having bugs. I hope Microsoft can solve the bugs before launch. In recent years, major Windows releases have rolled out with many bugs. It seems launching a massive platform running across hundreds of millions of devices simply means bugs are inevitable.
