The workaround refers to the following article:

changes to tokens if a user who's a member of the Administrators group in WINDOWS®XP or Windows Server 2003 logs on t o A computer, that user's token contains the Administrators group SID, and the user has the same permission as the Adminis Trators Group. In Windows Server-and Windows Vista, if UAC is enabled, the Administrators SID is still present in the token it is S ET to Deny only. When performing access control, such a entry in the token was used only to deny access - in other words, to match Deny ACEs. Any allow ACEs for that SID is ignored. That means that is not truly a administrator all the time, even if you log in to the computer as one
