Windows 10: Windows Security won't open, and when sometimes when I launch my pc and it's accessible, it...

Bonjour,J'ai tout essayé, malgré une réinstallation de windows 11, l'application Windows Security ne fonctionne pas. Il est accessible pendant un cour temps lorsque je lance le pc pas toujours, et lorsque je lui demande d'effectuer un full scan, il crash à un certain moment et impossible de le réouvrir.Le plus souvent j'ai l'icone Windows Security dans la barre des taches au niveau du "show hidden icon", où l'on voit l'icone avec un petit paneau Attention jaune pour mentionner un problème. Il ne s'ouvre pas et ne défends donc pas mon ordi.Merci pour votre aide

Windows Security won't launch

Sup people,

For some reason I don't seem to be able to launch Windows Security. The Windows Security icon on the taskbar is constantly showing a warning sign. If I try to launch Windows Security, a new app window would open but it'd just indefinitely show the Windows Security icon. I tried the steps suggested in this post (except for the complete OS reset) and nothing seems to work. For some reason I can't add any screenshots here so I'm hoping what I mean is clear enough.

Running Windows 11 23H2

P.S.: I recently sent in my laptop for repair and when I got it back a new "User" Windows account had already been set up. Thought this might also be relevant somehow.

Thank you

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Windows Security "Limited access by IT Admin"

Step 1:

• Download FixList.txt
  

• Save Fixlist.txt in the same folder where EnglishFRST64.exe is.
  
• Close all program windows.
  

• Launch the Farbar Scanner tool and click "Fix".
  
• Upload the output log file (FixLog.txt) to your OneDrive.
  
• Reboot Windows when prompted.
  

Step 2:

Ensure the system is connected to the internet.

From an admin Command Prompt, run:

• dism /online /cleanup-image /restorehealth
  

And then run:

• SFC /scannow
  

After the command completes, reboot Windows.

Open Windows Security and check the status of your antivirus.
