  Yes you are right, so do you have any sugestion/ideas how to do
  that on Windows XP SP2/NTFS/CYGWIN1.7. Does cyglsa in any way
  can help

  SYSTEM is only able to su to that users
  that are within its primary group thats Administrators/544
  so, what i did was i made test user member of SYSTEM/18 group
  thats how SYSTEM was able to su to test user. but thats not a
  good idea to make a regular user part of SYSTEM group.

  code to run as SYSTEM is, if you want to try it and can get any
  solution to this.=20

  cygrunsrv -I runassys -p C:/WINDOWS/system32/cmd.exe -a "/C start
  CMD.EXE /K C:\cygwin1.7\bin\bash.exe --login -i" -i --nohide
