GPO IE User Preferences Overwrite 1A10 reg key for Zone 4 to 1

    Question

  • This is our situation:

    OS: Windows 10 Build 1803
    Domain Controllers: Window 2008

    We are trying to set the following key to the value of 3:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\4\1A10

    We are also setting IE settings via preferences.

    We find that no matter what order we apply the registry key, it always gets overwritten.

    Here s a prcocmon capture

    Using the display XML option of the Internet Explorer preferences I found that the registry is being set within the preference to 1.

    I have tried exporting the GPO as a backup, editing it to change that reg key to 3, and re-importing it but every time i re-import it, it changes back.

    Does any one have any suggestions on how to get around this please or how to fix this?

  • I have found a fix.

    It seems once you click on a security zone within the preference settings, there are a set of default reg keys that are applied including the 1A10 key.

    The way around this was to recreate the preference and not click on the Restricted zone.

    Thanks
