Unable to fix Windows security.

Question

Hello,

A few weeks ago, I upgraded my laptop's SSD from 512 GB to 1 TB. Since then, I noticed that the only active protection software on my system is a third-party antivirus, while Windows Defender shows as "Unknown." When I restarted my PC, Windows Security (Defender) displayed the message: "Your IT Administrator has limited access to some areas of this app."

I searched online and watched several YouTube videos suggesting solutions like installing a security health ZIP file, updating policies, and deleting policies, but none of these worked for me.

Could someone please help me fix this issue? Also, I cannot reboot my laptop so please don't suggest that.

Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

This happens when there is a corrupted file in the Windows Defender folder or a reconfiguration is needed. First, you need to check if you have a work or school account:

Open Settings> Click Accounts> Click Access work or school, then disconnect the account there. If no account or are already disconnected, and you have the same issue, follow the steps below:

Note: Before doing the steps, I suggest completely uninstalling the third-party anti-virus first.

Method 1. Reinstall Windows Defender

Open the registry, then go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Then delete the Windows Defender folder, restart the PC, and recheck it.

Note: If the issue persists, a system repair on the affected device might be necessary. Please let me know the Windows version and edition you have.

To check:

Go to Settings > System > About

Under Windows specifications, please let me know the Windows version and edition you have.
