RUN AS window

I am getting a window that pops up for every program that I click on Called
Run As then asks which user account I want to use to open the program with a
box under it for protect my computer and data from unautorized activity--I
asked earlier and was refered to a solution that did not work and that was to
go to advanced in the shortcut properties and uncheck "run with different
credentials" this was ot checked to begin with any ideas?
