It then uses `wtfQueryUserToken`, and then calls `GetTokenInformation(TokenGroups)` on it. If one of the returned group's SIDs matches `CreateWellKnownSid(WinBuiltinAdministratorsSid)`, then it spawns the unprivileged UI process as that user token, passing it three unnamed pipe handles for IPC and the log mapping handle, as descried above. |
