Did you Recently Use Any Debloat Software?

If you recently used some kind of Windows debloat software there is a chance that this screwed something up deep within Windows. So if the tool you used has the option to rever or undo the changes see if that will work. If not it should have made a system restore point before you used it. So restore your computer using that restore point. If you aren't sure how here's a full guide: How to create and use System Restore Points on Windows 11. Or you can follow the quick steps below.

Note: System Protection must be enabled and restore points must exist.

• Press Windows + R
• Type rstrui and press Enter
• Click Show more restore points if available
• Choose a restore point dated before the issue began
• Follow the prompts and allow the PC to restart

If no restore points are available, proceed to the next step.

Update Windows

Microsoft has been doing a lot of "Vibe Coding" and using AI for stuff it should actually be taking seriously. As a result you may have got a bad update. So you can either uninstall the last update or try to get the latest update hoping either solves the problem. To force check for an update do the following.

• Open Settings
• Go to Windows Update
• Click Check for updates
• Install all available updates
• Restart your PC

If you want to uninstall an update check out this guide: How to uninstall a bad Windows 11 update. Rollback a Windows 11 update.

Repair System Files Using SFC and DISM

If system corruption is preventing Security Center from starting, use built in repair tools.

• Search for Command Prompt
• Select Run as administrator
• Run: sfc /scannow

When it's done run the DISM command.

If SFC reports it could not repair some files, run these commands one at a time:

Restart your PC after completion.

Repair or Reset Windows Security App

If Windows Security opens to a blank screen, the app interface may be corrupted.

• Open Settings.
• Go to Apps > Installed Apps.
• Scroll to the bottom and click System Components.
• Click the 3 dots and select Advanced Options.
• Finally click Repair and see if the problem goes away.
• If it doesn't go back and click Reset.
• Restart your computer.

Re Register Using PowerShell

• Open PowerShell as administrator and run:

• Restart the PC and test again.

Reset Windows

If corruption is severe or the service is missing entirely, resetting Windows might be your only option. This happens from time to time sadly. Don't forget to make a backup of all your data before you start.

• Open Settings
• Go to System and then Recovery
• Select Reset PC
• Choose Keep my files
• Select Cloud download or Local reinstall
• Confirm and wait for the reset to complete
