Issue with Windows Defender on Windows 11

[Asuka_Okami]

I cannot open any of the settings on windows defender, when i try to it tells me to look for a compatible app in the Microsoft Store. Is this a bug or some other (fixable) issue?

[#2]

Note; this was after a complete re-install of windows and happens to every other fresh install after (i tried to re-install 2 times trying to fix it)

@Asuka_Okami I am having the same exact issue.

same here , last update killed the link or overlay with windows defender .cant access any of the settings . same issue on laptop and home pc .

It's possible to reach the settings by using the search tool. Enter "Windows Defender" and you'll find a link to Windows Defender. You can also reach it from the control panel.

I have got the same issue. I can't even open it from the control panel or the setting menu.

Are you facing this issue with other Settings?
It looks like a bug and I advise you open the Feedback Hub app and report this issue.

Doesn´t work. Any click on any of the itens presented under "Protection Areas" prompts the appearance of this message: "You´ll need a new app to open this windowsdefender link", plus the option to "Look for an app in the Microsoft Store".

I found that running the steps here https://support.microsoft.com/en-us/topic/use-the-system-file-checker-tool-to-repair-missing-or-corr... resolved the issue, so it seems like the update corrupted some files.

No other settings work fine. Its just that windows defender wont open. I am going to report this. Thnx for the quick reply.

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

Thats for windows 10, and older, this post already said that it was using windows 11.

[#13]

This worked with me! Thank you very much!

[#14]

Worked! Thank you!

[#15]

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.

Thank you so much. It worked for me.

[#17]

Has anyone found a fix for this yet? I'm having the same issue. I can't install software for school because Windows Defender keeps deleting the files. The app is working fine and great so why can't we access it? It clearly exists

[#18]

Yeah, I have HP laptop and I did get PROCESS1_INITIALIZATION_FAILED on Windows RE
Running 22000.120

***FIX FOUND***
[I found a fix everyone!!]

Open PowerShell (as Administrator) and run this command (without the "")
"Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage"

After doing this, check your settings-> Privacy & Security-> Open Windows Security

This should open up Windows defender like it used to on Windows 10. I hope this fixes your problem.
