I notice a lot of reference to opening Power Shell and running a command or set of commands.
Up through Win7, I always did this sort of thing through Command Prompt (sometimes forced to run with elevated administrator privileges).
I don't know if Power Shell came in with Win8 or is new to Win10 and have never had occasion to use it.
What are the significant differences, if any, between these two beasts? I notice that Power Shell takes a lot longer to give you the prompt to start entering commands once the window is actually open than Command Prompt does.
