I was trying to get rid of all instances of a program that I uninstalled. I came across the "InprocServer32" key in the registry that had information about my uninstalled program and another entry called "ThreadingModel" with a value of "Apartment". Can/should I delete all values in the InprocServer32 key or just the one with my program information in it? I have seen alot of "InprocServer32" keys around in the registry....what is it for and what does the "ThreadingModel" do? Thanks in advance.
