the idea that’s under discussion is, one PC, one windows 7 OS running, and multiple user accounts running at the same time accessing multiple applications at the same time.
Basic windows 7 is not able to do what he wants especially with one of the users running world of warcraft which is a real resource hog.
-unless theres a secret tool that allows for multiple mouse/keyboard inputs at the same time and a secondary monitor and running wow in “windowed” mode.
I don’t know the first damned thing about Wow but what you are describing sounds like virtual desktops. This is a different concept than having multiple users. It sounds like you the ideal scenario would be to have WoW running windowed on a secondary monitor.
