I use Windows 7 Home Premium 64-bit and Steam version of the game, with virtual memory (swap file, if I understand you correctly) disabled. I run the game as administrator, same as you. The game starts one process, not two, checked this several times. When I tried to launch it in fullscreen mode, it often started minimized and didn't opened the window, this was resolved by setting the video mode to pseudo-fullscreen. I even tried to update the video drivers (and my Windows Aero interface now rests in peace).
