This policy removes the Administrative options from the Regional and Language Options control panel.  Administrative options include interfaces for setting system locale and copying settings to the default user. This policy does not, however, prevent an administrator or another application from changing these values programmatically.

The policy is used only to simplify the Regional Options control panel.

If the policy is Enabled, then the user will not be able to see the Administrative options.

If the policy is Disabled or Not Configured, then the user will see the Administrative options.

Note that even if a user can see the Administrative options, other policies may prevent them from modifying the values.
