);

The globally-unique identifier of the policy to set.

Remarks

Protected policies are process-wide configuration settings that are stored in read-only memory. This is intended to help protect the policy from being corrupted or altered in an unintended way while an application is executing.

To compile an application that calls this function, define _WIN32_WINNT as 0x0603 or later. For more information, see Using the Windows Headers.
