Windows Security is excellent, as it does its job pretty well; however, many Windows 11 users have been facing problems recently. According to a few users, the Windows Security app lacks the Protection History option.

For some, clicking the Protection History crashes their computer and does nothing. So, if you’re facing a similar issue, continue reading the article. Below, we have shared some simple steps to fix the Missing Protection History on the Windows Security app.

What is Windows Security Protection History?

Windows Security Protection History shows you all the actions that the security software has taken to safeguard your PC.

It will show you the scan results, the threats it has blocked, the threats that have been moved to the Quarantine folder, and more.

With the Protection History option, you can also allow the blocked apps, remove files from the Quarantine folder, and more. Basically, the option lets you view and revert the changes done by the security program.

Now that you know what the Protection History option on the Windows Security app does, it’s time to know how to fix the Protection History not opening issue.

1. Restart your Windows 11 PC

Maybe bugs or glitches prevent you from accessing the Windows Security protection history. You can eliminate such bugs & glitches by simply restarting your PC.

So, before you try the advanced troubleshooting, you can try restarting your PC and see if it helps. To restart Windows 11, click the Windows 11 Start button and select the Power Menu.

2. Disable any Third-Party Security Program You’re Using

The Windows Security app is set to turn off automatically once a third-party security program is detected.

So, chances are that your PC is using a third-party antivirus program as its default security tool; hence, the Protection History on the Windows Security app is empty.

To rule out this problem, you must disable or uninstall any third-party security program installed on your computer.

3. Clear Your Detection History Files

It’s possible that the existing Detection History files are corrupted; hence, they are not showing up in the Protection History screen.

1. Type Command Prompt in the Windows 11 Search. Next, right-click on the Command Prompt and select Run as administrator.

2. When the Command Prompt opens, execute these commands one after another:

del “C:\ProgramData\Microsoft\Windows Defender\Scans\mpcache*” /s > NUL 2>&1

del “C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service\DetectionHistory*”

del “C:\ProgramData\Microsoft\Windows Defender\Scans\mpenginedb.db”

That’s it! This should clear your existing detection history files. Make sure to restart your PC after executing these commands.
