Issue with Windows Defender on Windows 11
- I had this problem on all machines updated from 19043.1151 to 22000.120.
This command from elevated PowerShell fixed the problem for me, try it and report the results:
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

Thanks for everyone on this thread. This command finally worked for me.
Initially, I was getting errors with all the Appx commands. Turns out I had to use the built-in Windows PowerShell rather than the downloaded PowerShell Core in Windows Terminal. Hope this helps someone else beating their head against their monitor!
- This worked with me! Thank you very much!
- Worked! Thank you!
If you had this problem with build 22000.120 you probably also have the bug on (Shift + Restart)
Recovery advanced startup gets a BSOD PROCESS1_INITIALIZATION_FAILED, you should try and see if you have also that bug.- Yeah, I have HP laptop and I did get PROCESS1_INITIALIZATION_FAILED on Windows RE
Running 22000.120
It doesn't even work for me because it says I do not have the package installed. I opened windows PowerShell and ran Get-AppxPackage Microsoft.SecHealthUI -AllUsers and it said that InstallLocation is C:\Program Files\WindowsApps\Microsoft.SecHealthUI_1000.22000.1.0_neutral__8wekyb3d8bbwe
then I did go to C:\Program Files\WindowsApps\Microsoft.SecHealthUI_1000.22000.1.0_neutral__8wekyb3d8bbwe
and there was a .exe file and it didn't work.
- I had package not installed too. Try this from an elevated powershell:
add-appxpackage -disabledevelopmentmode -register ((Get-AppxPackage Microsoft.SecHealthUI -allusers).InstallLocation + '\AppxManifest.xml')- IT WORKED!!!
Thanks!
fggIBthanks for sharing this! I just upgraded to Windows 11 (Feb 2022) and my security app was "missing" as well but this command fixed it immediately for me!
Thank you so much. It worked for me.
- should try this command this really fixes that defender issues
- Powershell won't recognise that instruction on my hp laptop - even after repeated attempts - I've tried to reset computer to previous 11 version - again failed & Laptop even refuses to carry out a clean install of Windows 10 - I have even removed paid for antivirus programs in case of conflicts - did not help - appears this 18month old laptop
has become totally unprotected Windows 11 with no defender accessibility 😞 really need some professional help- I guess you need to install latest preview build 22000.120 again then see if it fixes
- This Worked for me.
but CPU consumption is generally high. - For me, This command is worked.
THIS ALSO WORKED FRO ME THANKYOU VERY MUCH
