Make the Lacros browser available

This setting provides several availability options for the Lacros browser.

If the policy is set to user_choice, the user can enable Lacros and make it primary. Lacros can still be disallowed with LacrosAllowed policy.

If the policy is set to lacros_disallowed, the user cannot use Lacros. LacrosAllowed policy is ignored.

If the policy is set to side_by_side, Lacros is enabled but is not the primary browser. LacrosAllowed policy is ignored.

If the policy is set to lacros_primary, Lacros is enabled and is the primary browser. LacrosAllowed policy is ignored.

If the policy is unset, the default is lacros_disallowed for enterprise-managed users and user_choice for non-managed users.

In the future it will be possible to make Lacros the only available browser in Google Chrome OS with lacros_only value.

Example value: lacros_primary

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
