In this tutorial, we will see how using a group policy, add a registry key.
With group policies, it is also possible to delete or modify the value of an existing key
Depending on the hive (HKLM / HKCU), the strategy should be placed on the correct OU (Organizational unit) and the correct computer or user configuration.
The registry settings are available in the Computer and User configuration.
In addition to placement, as I mentioned above, you must take into account the hive, if you want to apply a key to the hive (HK_CURRENT_USER) you must use the parameters of the user configuration.
It is possible to use the “hive” HK_CURRENT_USER \ .DEFAULT in the Computer configuration which allows you to apply the key for all new users who will log on to the computer, it is the equivalent of the default profile.
To illustrate the tutorial, the GPO which will be configured a key in the HKCU hive therefore on the user configuration.
