Disallow selection of Custom Locales

This policy prevents a user from selecting a supplemental custom locale as their user locale. The user is restricted to the set of locales that shipped with the operating system.

Note that this does not affect the selection of replacement locales. To prevent the selection of replacement locales, adjust the permissions of the %windir%\Globalization directory to prevent the installation of locales by unauthorized users.

Note that "Restrict user locales" can also be enabled to disallow selection of a custom locale, even if this policy is not configured.

If this policy is Enabled, then the user cannot select a custom locale as their user locale, but they may still select a replacement locale if one is installed.

If the policy is Disabled or Not Configured, then the user may select a custom locale as their user locale.

If this policy is Enabled at the Machine level, it cannot be disabled by a per-User policy. If this policy is Disabled at the Machine level, then the per-User policy will be ignored. If this policy is Not Configured at the machine level, then restrictions will be based on per-User policies.

To set this policy on a per-user basis, make sure that the per-machine policy is set to Not Configured.
