Description

The named pipe, \SUPipeServer, can be accessed by normal users to interact with the
System update service. The service provides the possibility to execute arbitrary
commands as SYSTEM if a valid security token is provided. This token can be generated
by calling the GetSystemInfoData function in the DLL tvsutil.dll. Please, note that the
System Update is stopped by default but can be started/stopped calling the Executable
ConfigService.exe.
