OK, if you do have admin privileges, there is one thing that can keep you from changing settings.
the first thing you should try is autoruns.
AutoRuns for Windows v8.73
try and disable anything you need to disable (be careful though
)
If you can disable something, and it "sticks", then it is not a system wide restriction. (the restrictions are only applied to msconfig)
If it is a system wide restriction, then you are most likely infected with smitware. We will have to remove the smitware first and then use registry keys to remove those restrictions.
by the way, there are two things that you should look for in autoruns
(1) printer.exe (usually in system32 folder in windows)
(2) or anything else that is not familiar (usually *.exe)
reply back and I will post the next steps
