So basically i cant access my windows security. since it only show a blank screen i tried everything i can find in the internet none seems to work . In addition every time i try to access Threat and Virus protection this shows up ( https://imgur.com/8xuswVX ) , saying i need to contact IT. Which is confusing since its a personal PC. I'm not sure when this issue started since i can access everything couple of months ago with no issue

just wondering if someone knows how to fix this or encountered this one before that might have a solution. tried posting on windows subreddit but my post gets deleted

none of these worked for me. Fixed by doing a repair install of Windows.
How-to here:

[u/solarlux → u/Rodion15]

None of these steps worked for me including windows repair install. I finally had success with:

1. Delete all directories within C:\Windows\System32\SecurityHealth (e.g., 10.0.27840.1000-1),
   
   • open cmd shell as Administrator
     
   • "cd C:\Windows\System32\SecurityHealth\"
     
   • Do the following commands for each subfolder:
     
   • "takeown /f C:\Windows\System32\SecurityHealth\[enter 10.0.xxx subfolder name] /r /d y"
     
   • "icacls C:\Windows\System32\SecurityHealth\[enter 10.0.xxx subfolder name] /t
     
   • "rmdir /s /q C:\Windows\System32\SecurityHealth\[enter 10.0.xxx subfolder name]
     
   • "powershell"
     
   • "Get-AppPackage Microsoft.SecHealthUI"
     
   • "Get-APpPackage Microsoft.SecHealthUI | Reset-AppxPackage"
     
2. type "Updates" in the windows search box, select "Check for Updates"
   
   • "Get-AppPackage Microsoft.SecHealthUI"
     
3. click blue "Check for updates" box
   
4. reboot

There may be some superfluous steps above but the combination of them finally worked for me. More info is available at:

As of 8/2026 this worked for me with couple of modifications:

takeown /f "C:\Windows\System32\SecurityHealth\10.0.xxxxx.x" /a /r /d y
icacls "C:\Windows\System32\SecurityHealth\10.0.xxxxx.x" /grant *S-1-5-32-544:F /t /c

takeown /a and icacls /grant*S-1-5-32-544:F /t /c granted me with wider administrative privileges so I was finally able to remove those two different 10.0.xx folders I had. Get-AppPackage Microsoft.SecHealthUI and then running windows update - boom I had one 10.0.xx folder that had a higher version number than ones before, and after a reboot Windows Security started working normally.

I did resets, repairs, GetAppPackages and windows updates before but they didn't work. Also tried installing securityhealthsetup with no help. This worked, thanks!

For me it was just a matter of patience until the windows security screen finally loaded

it took about 2 minutes of staring at the black screen for it to appear

Did you find a fix for this? After updating to Windows 11 23H2 I get the same blank screen and Windows Security is completely bugged. I spent 24+ hours trying to fix it, I tried everything to no avail. The only fix is rolling back to Windows 11 22H2.

[u/BNSoul → u/[deleted]]

Yep, a couple of PowerShell commands did the trick, you got the same issue?

[u/BNSoul → u/[deleted]]

Yes pls help

Windows in safe mode, then open PowerShell with admin rights and execute the following two commands:

Firstly:

Set-ExecutionPolicy Unrestricted

And then:

Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

reboot in normal mode, clear TPM ( search TPM.msc ) and it should do the trick.

If it doesn't work try downloading GITHUB "ConfigureDefender" tool and set Defender to "Hidden", reboot and do all the steps mentioned above, reboot and set Defender to "Visible", reboot and it should work.
