Thanks Bart I did find the executable and did the policy great idea and
thanks Russell for original idea that worked, is everyone using locked down
local accounts how do you manage software that thinks they need this access
and is there software to help setup local restrictions but still allow
software access thanks everyone after a month of work(well plus usually pc
and admin stuff) I am regaining control. Good fuel to start locking down
stuff and hopefully some sans training or m/aybe better microsoft forefront
training.thanks again.

patched not just MS products (removal of unneeded software makes this
easier), disable unneeded services, use different administrator passwords
for each local machine if possible (to stop worms and pass the hash),
segment critical machines (911) from web surfing machines on the network,
etc. *user education *. Use this episode to illustrate the risks. (do you
really want someone to die because 911 is down because you infected your
machine playing Farmville?)
