In the aftermath of a malware attack, the Windows Defender Security settings page may show the message Some settings are managed by your organization or This setting is managed by your administrator. The real-time protection and cloud-based protection options may remain disabled or grayed out.
Here is what the Windows Defender Settings page might look like. The controls for real-time protection, cloud-based protection, and Automatic sample submission options may be disabled and locked down or grayed out.
If you’ve installed a 3rd party anti-virus, Windows Defender gets disabled automatically. It’s normal. In that case, you’ll see the message “You’re using other antivirus providers.” instead.
If Microsoft Defender group policies or registry-based policy settings are in effect, the following error appears when opening the Security at a glance page:
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.
Virus & Threat Protection is Missing?
In some situations, the Virus & threat protection section may be missing. The Virus & threat protection section in the Windows Security user interface lets you configure every aspect of the Microsoft Defender Antivirus — such as real-time protection, tamper protection, ransomware protection, Controlled folder access, and other important settings.
Malware and viruses may add registry entries that hide the Virus & threat protection section from the user interface. This is caused by some registry-based Policy settings. (Jump to this part.)
This post tells you how to activate Microsoft Defender real-time protection and other settings by removing the entire Microsoft Defender Antivirus registry-based policies previously added by malware, a 3rd party tweaker, or a privacy protection tool. The “Virus & Threat Protection” section should also be restored automatically after removing all the Policies.
Third-party privacy protection tools
If you have used third-party anti-spy tools such as O&O ShutUp, make sure you reset all “Windows Defender and Microsoft SpyNet” settings in that program.
Connected to Domain/Azure AD?
If you’ve connected your computer to a domain or work/school account, please contact your IT administrator or disconnect the system from the work/school account.
Or disconnect from your Work/School/Azure AD by opening Settings → Accounts → Access work or school and click on your Azure AD account, and click Disconnect.
Malware can add registry entries that disable the real-time monitoring capabilities of Windows Defender, and also hide certain parts of the Windows Defender user interface from users.
First, make sure you eliminate malware with help from an expert or friend — given the complexity of the malware infestation, professional help may be suggested. You may also try Windows Defender Offline. in addition.
The malware removal procedure is complex and is beyond the scope of this article. After eradicating the malware, remove the registry-based policy settings added by malware.
Virus and Threat Protection missing?
If the Virus & threat protection section is missing in the Defender user interface, it may be caused by one of the following group policy settings:
Enable the headless UI modegroup policy setting (Registry value:
Hide the virus and threat protection areagroup policy (Registry value:
- A registry-based policy — value named
The following are the registry values that hide the Virus & threat protection category in the Windows Defender Security user interface.
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\UX Configuration] Value: UILockdown [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender Security Center\Virus and threat protection] Value: UILockdown [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Policy Manager] Value: AllowUserUIAccess
Clearing the above policies especially should reinstate the Virus & threat protection option back. The “
defender-policies-remove.reg” registry file below removes all the Microsoft Defender Policies and restores the Virus & threat protection section as well.
Remove All the Microsoft Defender Policies
Option 1: Remove Microsoft Defender Registry-based Policies
gpedit.msc) on the local computer, you need to follow “Method 2” to remove the Policies.
Automate the following registry modifications using defender-policies-remove.reg (zipped). Unzip and run the enclosed REG file. After running it, you may want to open the Registry Editor to ensure the “Windows Defender” Policies key doesn’t exist. Once done, restart Windows for the changes to take effect. If you’re unable to apply the above registry file, launch Windows in Safe Mode and try merging the file again.
To manually remove Microsoft Defender Antivirus policies using Regedit:
- Start the Registry Editor (regedit.exe) and go to the following branch:
- Export the branch to a .reg file.
- Right-click “Windows Defender” and choose Delete.
- Similarly, backup the following branch (if exists) to a .reg file:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Advanced Threat Protection
- Delete the “Windows Advanced Threat Protection” key.
- Next, backup the following branch (if exists) to a .reg file:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender Security Center
- Delete the “Windows Defender Security Center” key.
- Exit the Registry Editor.
- Restart Windows.
Note that this completely clears the policy settings for Microsoft Defender Antivirus and Windows Security page. By default, in a clean installation of Windows, no policies are set for Defender.
After removing all the policies, you may want to enable PUA or adware protection in Windows Defender. If you had already enabled the setting before, you’d need to redo the procedure now.
Option 2: Remove Windows Defender Policies using Group Policy Editor
If you have previously enabled Defender Policies using
gpedit.msc (Windows 10/11 Professional or higher editions), you’ll need to use the same tool to remove the policies. The relevant Microsoft Defender Antivirus Group Policies are available in the following branch of the Group Policy Editor (
Computer Configuration → Administrative Templates → Windows Components → Microsoft Defender Antivirus Computer Configuration → Administrative Templates → Windows Components → Windows Security
Note that in earlier versions of Windows 10, the policy settings would be located under “Windows Defender” instead of “Microsoft Defender Antivirus”.
There are 100+ policy settings in Windows 10/11, with the items in every sub-branch put together.
Running the Resultant Set of Policy utility (
gpresult /h <path>\gpreport.html command shows you which policies are currently enabled.
You need to make sure they’re set to “Not configured.”

and download the latest update
