The Group Policy Editor is not available in all versions of Windows 10. The Windows 10 Home version does not come with the Group Policy Editor. That is why we have included the Registry Editor method for a similar setting.
Method 1: Using the Local Group Policy Editor
The Group Policy is a Windows feature through which users can configure different types of settings for their operating system. There are many settings in Group Policy Editor for hiding any specific settings in your Settings app. It also has a setting for hiding the Device Security area in the Windows Defender Security Center. If you enable the setting, then this section will no longer appear on the home page of the Windows Security app. It will also not show the icon on the navigation bar on the side of the Settings app. The requirement for this setting is to have at least Windows 10 version 1803 or Windows Server 2016. Check the below steps and see how it works: Note: If you are using the Windows Home edition, then skip this method.
Method 2: Using the Registry Editor
The Registry Editor is another method for hiding the Device Security section of the Windows Defender Security Center. If you already used the Local Group Policy Editor method, then this will already have the value configured. If you are directly using this method, then you need to create the missing keys and value to configure the setting for your system. It is a bit technical compared to the Local Group Policy Editor method, however, by following the below steps you can easily configure it:
