GPO settings are not listed (as they should per Microsoft article)

You may notice that the settings to be configured by GPO are not listed in your configuration.
The reason of that: specific settings are issued with KB update that got installed on the domain controllers, but not into the SYSVOL location of domain controllers.
To fix the issue you have to manually move the new policy definitions files to the proper location:

1. Copy @.adml file from c:\windows\policydefinitions\en-us to your local sysvol location under sysvol\policydefinitions\en-us.
2. Copy @.admx file from c:\windows\policydefinitions to your local sysvol location under sysvol\policydefinitions.
