4592-RestartManager-AddPriviledges

If the named process is running under another user, then OpenProcess must be called using a process token which includes SeDebugPriviledge.  To set SeDebugPriviledge the caller must have elevated privileges.  If cannot set SeDebugPriviledge, log a message and continue.  Let caller handle a reboot request rather than returning a failure.
