Different anonymous, but I will answer your question marymax: 'Why doesn't PA have a standard Desktop?'

Define a standard OS image?  With more than 40 Departments with varying level of budgeting and resources and more variations of software than most organizations could even imagine, what would a 'standard OS image be'?  If it is simply defining through policy OS standards, patching requirements, AV and other security software requirements that make up a required base of an image...than yes, this all exists.  I do not have the animosity by Anonymous the first for Bob...he was a good guy in a tough position IMHO
