When your environment migrates from legacy or lower version of Windows Server to a newer version. Example, from Windows Server 2008 to Windows Server 2016. You will experience this. This is why I am writing this post.
I notice when I launch the Group Policy Management and direct to one of the Group Policy Object > Settings Tab > Show all and saw a part says “Extra Registry Settings“. I open up the Edit, trying to locate that part but failed to do so. What I did is I research on the browser, checking whether has anyone experience it and what are the solutions to it.
There is a message display inside the “Extra Registry Settings” but not helpful in getting any information in the browser. The message is “Display names for some settings cannot be found. You might be able to resolve this issue by updating the .ADM files used by Group Policy Management.”
Thank god that PowerShell can remove this registry using the Remove-GPRegistryValue Command. You may refer to the reference below too.
First I run the GET command just to make sure the registry value is valid;
#This command retrieve information of an extra registry of the
Get-GPRegistryValue -Name "<GPO Name>" -Key "HKLM\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\"
#If result is valid then move on to REMOVE command, note that sensitivity on the Key Path Value "\" at the end must not be included
Remove-GPRegistryValue -Name "<GPO Name>" -Key "HKLM\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\" -ValueName "<Registry Value Name>"
#A result will be shown after the REMOVE command executed, result contain GPO Name, Owner, creation time and modification time
To those are newbie to GPO (Group Policy Objects) or Group policy management, your mentor sure told you to not configure default domain policy and instead they will tell you to create a new GPO.
Here is something you should know, “Not all policy settings are workable under newly create GPO”. This means that there are still dependencies with Default GPOs. Even you’ve try to enable “Enforce” or “Block Inheritance”, the Default GPO will always there running. Thus, always research and understand in-dept of GPO.
