Windows 11's Windows Security App can't open.
Alright guys, just now I'm trying to disable the Windows defender but I found out that I can't even open the Windows Security App. Anyone knows what's going on? Any solution? I'm looking for help. 
Hello,Suggest try the following steps:
- Open PowerShell by using Administrator rights
- Copy and paste Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage to the PowerShell window and press enter
- Close the PowerShell and retry
JianYuIf nothing works this might work.It worked for me. Go to C:\Windows\System32\SecurityHealth
.Go to the first folder(usuallay an version folder) and install all APPX files in the folder.To install run them as administrator and follow as instruction are given.
ll the options I could find didn't work.
- Hey I started having this issue recently and was wondering if it had something to do with system configuration because when I go to System Configuration and it tells me that the status of the service is stopped for windows security. I have also tried many fixes, I tried uninstalling apps to see if anything was conflicting with it, I tried repairing through PowerShell, I tried repair corrupt files through Command Prompt, I tried repairing and restarting through windows settings, and I got nowhere with any of those fixes. I also cannot access the windows security tab in Settings and when I click on it. It just causes my Settings to become unresponsive. I was wondering if this has something to do with my system possibly being compromised or if it's purely a windows 11 issue.
- Ive been doing this fix for a while now and I just noticed that the actual problem is that windows security app can't open.... My opens but I cannot access virus and threat protection. Is this problem related to that or completely different? I tried support and thought that I had a school or work account since the message says "Page not available: Your IT administrator has limited access to some areas of this app, and the item you tried to access is not available. Contact IT helpdesk for more information." but this happened a 1-2 months ago and its windows insider update related. Basically I wanna ask if this is related to windows security not opening or not?
- I've tried the resetting, re-installing, and other tips in this thread and I still cannot launch the Security App. I just get a blank window with the Security App icon in the middle.
I have Acronis Cyber Protect Home Office and have disabled the protection but the situation is still the same. - windows has a serious problem that affects the functioning .... unwanted viruses ... because a common user would need to execute a system file (use it) like a .bat, a (.pif) or a (.vbe) these are unnecessary things, there should be a windows "(armored) windows for ordinary users should only open and close programs and windows and end this business instead of running .exe programs manually the installation packages .then... because an ordinary person without a technical level could do it this windows is losing its space for the public. poddria having a customized windows only for those who deal with t.i, students, and common people who don't know how to program. .avoiding virus invasions... those who want to make apps for windows, these apps, be examined by microsoft and then released to the public but released through the microsoft app store and only through the app store @*just like the linux playstore. I hope to be heard here. by
This is a really strange issue, I can see the app in the notification area but when I click on it nothing happens, when I go in through settings the "You’ll need a new app to open this windowsdefender link" error comes up.
I tried all of the "Get-AppxPackage" commands without success, I also tried running sfc /scannow and dism restorehealth and nothing changed.
When I try the command with the "WindowsApps" folder it says the specific path for "Microsoft.SecHealthUI" can't be found, it's like it is completely missing from the Windows 11 install but Windows thinks there's nothing wrong.
The only way I could fix it was to do a complete wipe and reinstall of Windows 11.
- The real solution is to go back to Windows 10 !
Microsoft has real bad programmers as of late. They botched the forced upgrade of windows 111 on my surface pro. Totally useless. Everything has high cpu usage.
